In this problem, you there are only 2 different sets of measurements.
Angles 1, 2, 7, 8 are all the 30 degree angles. They are alternating interior angles of parallel lines cut by transverals.
Angles 3, 4, 5, 6 would be 150 degrees, because they are supplementary (add to 180) with the adjacent angles.
Answer:
<em> Length of guy wire is 590.6 ft</em>
Step-by-step explanation:
The complete question is
A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to be attached 8 feet from the top and is to make an angle of 20° with the ground. Give your answer to the nearest tenth of a foot.
height of tower = 210 ft
8 ft fro the top leaves 210 - 8 = 202 ft to the ground
This is an angle of elevation problem
the opposite is 202 ft
hypotenuse = ?
angle is 20°
using sin ∅ = opp/hyp
sin 20° = 202/hyp
0.342 = 202/hyp
hyp = 202/0.342 = <em>590.6 ft this is the length of the guy wire</em>
Answer:
Step-by-step explanation:
The tangent ratio is the ratio of the length of the opposite side to the length of the adjacent side.
This implies that;
The length of the side opposite to the 74 degree angle is 24 units.
The length of the side adjacent to the 74 degree angle is 7 units.
We substitute these values into the formula to obtain;
The correct answer is option F
Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.
Step-by-step explanation:
Divide the top and bottom by 2.
14 / 2 = 7
16 / 2 = 8
7/8
