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.

1/2x+5=10 whats the value of the variable

svlad2 [7]

Answer:

1/2x+5=10

subtracting 5 from both sides 1/2x+5-5=10-5

1/2x=5

divide both sides by 1/2

1/2x÷1/2=5÷1/2

x=5×2/1

x=10

Rachel is typing a 1,500-word report. Her progress is represented by the equation. 1,500 = 500 + 50t, where t is the number of m

Rudiy27

To calculate this you’ll have to subtract and then divide
1500= 500+50t
1.) subtract 500 from 1500 to break down the equation
1500-500 =500+50t -500
1000= 50t
2.) now you want to get t alone... so since t is multiplied by 50, you will do the opposite and divide 50 from 1000 in order to get rid of it- which will again break down the equation
1000 /50= 50t /50
20= t

The answer is 20 minutes
Hope this helps x
