Answer:
f(-9) = -263
Step-by-step explanation:
Find f(-9) by plugging in -9 into the function, and simplifying it:
f(x) = -3x² - 20
f(-9) = -3(-9)² - 20
f(-9) = -3(81) - 20
f(-9) = -243 - 20
So, the answer is f(-9) = -263

I hope this helps!
take 55 degree as reference angle
using tan rule
tan 55=opposite/adjacent
1.42=37/x
x=37/1.42
x=26.05
