Angle A is 45
Angle R is 72 because S and R are the corresponding angles in the triangle.
To find angle RVA add 72 and 45 and the subtract by 180.
RVA = 180-(72+45) = 63
Hope this helps :)
Answer:
34.5 units²
Step-by-step explanation:
7 x 3 = 21
4.5 x 3 = 13.5
21 = 13.5 = 34.5 units²
Hi there
(-20x + 21)/2
-10x + 21/2
I hope that's help !
Simply put 10 in all of the boxes. There are 5 boxes. And all those boxes equal 50, right? So for every box, there's 10 students. 10 multiplied by 5 is equal to 50.
Step-by-step explanation:
for a
- a+,38°=90°{ angle at circumference through center is 90°}
- a=90-38
- a=52°
for e
- e=38°{base angle of isosceles triangle r equal}
for d
- 38°+e+d=180°{sum of angle of triangle}
- d=180-76
- d=104°
for. c
- c+d=180°{straight angle}
- c=180-104°
- c=76°
for b
- a+b+c=180°{sum of angle of triangle}
- b=180-128
- b=52°
hope it helps.
