Answer:
m<T = 60°
m<U = 60°
TS = 13
SU = 13
Explanation:
Triangle TSU is an equilateral triangle.
All interior angles has equal measures and each = 60° since the sum of interior angles in a triangle is equal to 180 and this divided by 3 = 60
all side lengths are also equal to one another, TU is given as 13 cm so the length of TS and SU is also = 13
