Answer:
a) x = 20, b) h = 15
Step-by-step explanation:
a) 17² - 8² = x² x = 15, which is the height of the triangle, next, 25² - 15² = x²
x = 20
b) The way I would solve this is I'd find the measure of angle Q first.
a²=b²+c²-2bc cos A
39²=44²+17²-2(44)(17) cos A
-704 = -1496 cos A
inverse cos(-704/-1496) = A
A = 61.93°
Then sin 61.93 = h / 17
h = 15
