Answer:
25.8 ft
Step-by-step explanation:
Draw a right triangle with the right angle at the foot of the tower. The interior angle of the triangle at the top is the complement of the angle of depression. 90 - 74 = 16; it measures 16°. The leg at the bottom has length x. The height of the tower is the vertical leg and is 90 ft. We are looking for x.
For the 16° angle, x is the opposite leg, and 90 ft is the adjacent leg.
tan A = opp/adj
tan 16° = x/(90 ft)
x = 90 ft * tan 16°
x = 25.8 ft
Answer: 25.8 ft
Answer:
O Prime
Step-by-step explanation:
x^2 - 7x - 10
What two numbers multiply to -10 and add to -7
There are no two number that multiply to -10 and add to -7
The students baked 19 pies. Cafeteria-9*8=72 slices of pie 224-72=152 152/8 is 19 ,19 pies
We know that for this equation, 360 is going to be our total. If the skyway's main span is 30 meters shorter, we will be subtracting 30 from whatever our x value is, as shown here:
360 = x - 30
To solve for x, we must do the opposite of the operation we see. The opposite of subtracting 30 is adding 30. So we must add 30 to both sides of our equation.
360 + 30 = 390
So,
x = 390
This means that the length of the main span of the dames point bridge is 390 meters. <span />
