Answer:
41.4feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Given the following
Distance of Rafael from the tower = 55feet = Adjacent
Angle of elevation = 37degrees
Required
Height of the tower = Opposite
Since Tan theta = opp/adj
Tan 37 = x/55
x = 55tan37
x = 55(0.7536)
x = 41.4
Hence the tower is 41.4feet up the viewing platform
Answer:
48
Step-by-step explanation:
x = -2 y =3
3x² - 2xy²
3(-2)² -2(-2)(3)²
square first
3*4 -2(-2)*9
multiplty from left to right
12-2(-2)*9
multiply from left to right again
12 -(-36) subtract using rule for integers that double minus is plus
12 + 36
48
