Answer: The angles are 80 and 100.

Step-by-step explanation:

Total angles for a supplementary angle is 180°.

Since the angles are in 5:4

5/9 × 180= 100

4/9 × 180= 80

The angles are 100° and 80°.

Step-by-step explanation:

Given,

Two supplementary angles are in ratio 5:4

To find the value of each angle.

Let,

Two angles are 5x and 4x.

For supplementary angle sum of two angles is 180°

So,

5x+4x = 180°

or, 9x= 180°

or, x = 180÷9

or, x = 20°

The angles are 100° and 80°.

Talja [164]

I think the answer is 25 miles.
6+4+.7x= 27.50
10+.70x= 27.50
.70x= 17.50
Divide both sides by .7 and the answer is 25.

<u>Step-by-step explanation:</u>

A blimp provides aerial television views of a baseball game. The television camera sights the stadium at a 12° angle of depression. The altitude of the blimp is 300 m. We need to find What is the line-of-sight distance from the television camera to the base of the stadium . Let's find out:

According to question , given scenario is in a right angle triangle where

$Perpendicular=300\\Hypotenuse=?\\x=12$ , where x is angle of depression.
