A.) The mean of the 8th and 9th values
20t² - 13tv - 15v²
20t² - 25tv + 12tv - 15v²
(5t + 3v)(4t - 5v)
I think it must be the right triangle so
x=height of the antenna
tan(66)=x/50
x=50*tan(66)
x=1.33 ft
->the height of the antenna = 1.33 ft
hope it is the correct answer because you didn't provided me enough information.
T= 60°
It is an equilateral triangle which means all sides and angles are equal
u= 10m
It is an equilateral triangle which means all sides and angles are the same
I dont remember that one sorry
