Question

In ∆ RST, angle S is a right angle and angle R is 10° greater than angle T. What is the measure of angle T?

(A) 40° 
(B) 45° 
(C) 50°
(D) 55° 
(E) 80°

doomedcat · Answer

90+T+(T+10)=180
T=40

sun90 · Answer

Ans : a - 40 degree

Let angle T be x . Thus angle R= x+10
Some of all the sides of the traingle is 180 degree

GOing by this , x+x+10+90 = 180 degree . Thus x=40 degree

Thus x = 40 degree

kunalsinghNS · Answer

R = T +10

and S+R+T = 180

We know S = 90

Hence, the above equations we get T = 40

Answer = A

septwibowo · Answer

1. The remaining angles should be 90 degree.
2. So, R + T should be 90 degree.
3. Since R = 10 + T, so (10+T) + T = 90, thus T = 40 (and R is 50).
