Step-by-step explanation:
the angle at R is the same on both sides of R (meaning in both triangles).
so, the angle at Q is
180 - 85 - 40 = 55°
based on the naming sequence of the congruent relation we see that P relates to W. and Q to T.
so, the angle at T is the same at Q = 55°
Answer:
There is no solution for C.
Step-by-step explanation:
Answer:
QT = 16
Step-by-step explanation:
ΔQRS ~ ΔQRT
In similar triangles, corresponding angles are in same ratio.

Cross multiply,
QT * 25 = 20 * 20

S(x) = x^3
Make x the subject:-
x = (S(x))^ 1/3 = ∛ S(x)
Inverse is ∛ S(x)
17.652 is the answer of radius
