Answer:
QSR = 68º
Step-by-step explanation:
TSQ + QSR = TSR
15x + (10x - 2) = 173
Combine like terms
25x = 175
Divide both sides by 25
x = 7
QSR = 10x - 2
QSR = 10(7) - 2
QSR = 68º

Answer:
C. 17 inches
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of s
a^2 +b^2 = c^2
where a is 1/2 l
a = 1/2 (16) = 8
b = h = 15
c =s
8^2 + 15^2 = s^2
64 +225 = s^2
289 = s^2
Take the square root of each side
sqrt(289) = sqrt(s^2)
17 = s
