Alex is standing 60 feet from the base of a flagpole. He measures the angle of elevation to the top of the pole as 35º. Vera is

ivanzaharov [21]

Answer:

49.4 degrees

Step-by-step explanation:

In Triangle AXY,

$Tan 35^0=\frac{|XY|}{60} \\|XY|=60*Tan 35^0=42.01\:feet\\$Therefore, Height of the pole=42.01 \:feet$

We want to determine the angle of elevation from the point Vera is standing to the top of the flagpole, which is the angle at V in the diagram.

In Triangle XVY

|VY|=36 feet

$Tan \theta=\frac{|XY|}{|VY|} \\Tan \theta=\frac{42.01}{36}\\ \theta=arctan(\frac{42.01}{36})\\ \theta=49.4^0$

Therefore, the angle of elevation from the point Vera is standing to the top of the flagpole is 49.4 degree to the nearest tenth of a degree.

Choose the correct graph of the function y=-1/2√x+3+2

Bad White [126]

Find y intercept

$\\ \rm\rightarrowtail y=-\dfrac{1}{2}\sqrt{x+3}+2$

$\\ \rm\rightarrowtail y=-\dfrac{1}{2}\sqrt{0+3}+2$

$\\ \rm\rightarrowtail y=\dfrac{-\sqrt{3}}{2}+2$

$\\ \rm\rightarrowtail y=\dfrac{4-\sqrt{3}}{2}$

$\\ \rm\rightarrowtail y=\dfrac{4-1.732}{2}$

$\\ \rm\rightarrowtail y=\dfrac{2.368}{2}$

$\\ \rm\rightarrowtail y=1.184$

y intercept=(0,1.2)

Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided.

qaws [65]

7(x-2) + 3(x + 2) = 5(x-6)...distribute thru the parenthesis
7x - 14 + 3x + 6 = 5x - 30...combine like terms
10x - 8 = 5x - 30...subtract 5x from both sides
10x - 5x - 8 = -30....add 8 to both sides
10x - 5x = -30 + 8...combine like terms
5x = - 22
x = -22/5 = - 4 2/5 <==
