An angle measures 14° more than the measure of its supplementary angle. What is the measure of each angle?
luda_lava [24]

Answer:83 and 97

Step-by-step explanation:

Let the angle be y

The second angle will be y+14

A supplementary angle equals 180°

y + y + 14=180

2y+14=180

2y=180-14

2y=166

y=166/2

y=83

The first angle is 83.

Second angle will be 83+14=97.

leva [86]
The tree is 25 feet tall. Given the height of the stick and the shadow it cast, the angle formed by the sun and the stick's height can be obtained by taking the Inverse Tangent of 3/5. This is equal to 30.93. This angle is equal to the angle formed by the sun and the tree's height. Using the tangent formula, Tan (30.93)=tree's shadow (15 ft)/ height of the tree, giving the answer 25 feet.
