SAS is a congruency criteria which is used to prove that two triangles are congruent, if two corresponding sides and an angle between them is equal in both the triangles.
For example - In the attached picture,
KL = XY
∠KLM = ∠XYZ
LM = YZ
Therefore, ΔKLM ≅ ΔXYZ
(By SAS criteria)

A triangle has side lengths of 6, 8, and 10. Is it a right triangle?
Answers
Answer: Yes
Step-by-step explanation:
You can tell that two of the numbers are only 2 apart, hence CB and CA, and the other one, AB, or the bottom side, is way less.
Answer:
YES IT IS
Step-by-step explanation:
For a triangle to be a right triangle, it must follow pythagorean theorem to find the hypotenuse (long side of triangle).
A squared + B squared = C squared
6 squared + 8 squared = 100
Since we squared our addends, we must find the square root of 100 (which is 10)
Since 10 is one of the side lengths for the hypotenuse since it is the longest, and we got 10 from pythagorean theorem, we know it is a right triangle.

3(x + 4) - 10 = 1/10 (4x + 16)
3x + 12 - 10 = 2x + 8
3x + 2 = 2x + 8
5x + 2 = 8
5x = 6
X = 6/5
Answers
3(x+4)-10 = 1/10 (4x+16)
3x+12-10 = 1/10*2 (2x+8)
3x+2 = 1/5* (2x+8)
3x+2 = 2/5x + 8/5
15x+10 = 2x+8
15x-2x=8-10

The measure of Angle G is 41
Step-by-step explanation:
We know that in a parallelogram, opposite angles are congruent, therefore let's solve for x-value first;
3x + 11 = 5x - 9
11 = 5x - 3x - 9
11 = 2x - 9
11 + 9 = 2x
20 = 2x
20/2 = x
10 = x
Now that we have x-value, we can substitute it in the equation for Angle G to find it's angle measure;
5(10) - 9 = ∠G
50 - 9 = ∠G
41 = ∠G
So the final answer = The measure of Angle G is 41

what is the reciprocal of 24
Answers
Answer:
-1/24
Step-by-step explanation:
To find the reciprocal, you swap the numerator and the denominator. In this case, the numerator is 24 and the denominator is 1. Therefore, it would be 1/24. Now all we have to do is make this number negative. This would make it -1/24. Therefore, the reciprocal of 24 is -1/24.

What are trigonometric identities?
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Since the triangle has a right angle, we can find the length of the unknown side using the trigonometric notations SOH CAH TOA where;
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side and CB is the hypotenuse side, DC is the opposite side
Hence ,Sin B = 15/17

If 8 bags of grapes cost $20.00, how much do 3 bags of grapes cost?
Answers
Given that eight bags of grapes cost twenty dollars, the cost of 3 bags of grapes will be $7.5.
How much do 3 bags of grapes cost?
Given that;
8 bags of grapes cost $20.00
First, we find how much each bag of grape cost
8 bags = $20.00
1 bag = x
x = $20.00 / 8
x = $2.5
Now, if 1 bag of grapes cost $2.5
3 bags of grapes will cost y
y = 3 ×$2.5
y = $7.5
Given that eight bags of grapes cost twenty dollars, the cost of 3 bags of grapes will be $7.5.

what are the amplitude period phase shift and midline for F(x)=-4cos(3x-3.14)+2
Answers
Answer:
Step-by-step explanation:
f(x) = -4cos(3x-pi) +2
compare to f(x) = A cos (B(x+C))+D
A is amplitude =4
Period is 2pi/B so period = 2pi/3
Phase shift is C so phase shift = -pi (this could be positive if it shifted to the left)
Midline is at D so midline is y=2

13.2 Area of Triangles
2. Find the area of the triangle.
14 ft
17 ft
Answers
Answer:
119
Step-by-step explanation:
Answer:
question 1 is, the area is 119
question two is, the base length is 18
Step-by-step explanation:
PART ONE
To figure this out we need to know that to find the area the equation is A=1/2bh so lets create our equation
A=1/2(17)(14)
A=1/2(238)
A=119
119 is your area
PART TWO
to find out the length we need to basically reverse what we did in the first part
270*2=540
540 divided by 30 (the height)=18
18 is the base length
to show it is correct we can use these numbers to find the answer
A=1/2(18)(30)
A=1/2(540)
A=270
