Answer:
R is 51 degrees
P is 51 degrees
Q is 78 degrees
Step-by-step explanation:
This is an isosceles triangle so R and P are the same angle degree.
First set them equal to each other to be (4x+23)=(2x+37) to get x=7.
Substitute X with 7: 4(7)+23=2(7)+37. It will be 51=51.
A triangle is equal to 180 degrees so 51+51 is 102 and 180-102 is 78.
Hope this helped :)
Answer:
x=3
Step-by-step explanation:
2 triangles are proportional so we have
4/6=x/4,5
--> x=(4.4,5)/6=3
You can also use sin cos but this way is faster

Answer:
x = 12
z = 101
Step-by-step explanation:
Hello There!
First lets find z
Well the angle that has a measure of 79 degrees and angle z are supplementary angles meaning that the sum of the two is 180
So we can find the missing angle by subtract the given angle (79 in this case) from 180
180 - 79 = 101 so z = 101
Now lets find x
The angle that has a measure of 79 degrees and the angle labeled (6x+7) are vertical angles
If you didn't know vertical angles are congruent
That being said lets create an equation to solve for x
79 = 6x + 7
now we solve for x
step 1 subtract 7 from each side by
7 - 7 cancels out
79 - 7 = 72
now we have 72 = 6x
step 2 divide each side by 6
72/6=12
6x/6=x
we're left with x = 12
Answer:
x = 53
Step-by-step explanation:
x = 53 because they are alternate exterior angles
