Answer:
<em>The porch is 7.35 feet off the ground</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The ramp, the height of the porch, and the distance from the base of both form a right triangle where trigonometric ratios can be applied.
The angle of 20° has the height of the porch H as the opposite side, and the hypotenuse is the length of the ramp.
The sine is defined as:
For our problem:
Solving for H:
Find the sine of 20° by using a calculator:
H=7.35 feet
The porch is 7.35 feet off the ground

<u><em>Answer:</em></u>9
<u><em>Explanation:</em></u>To get the fraction of a number, you will simply multiply the fraction by the given number.
For the given, we want to find </span>
<span> of 45.
<u><em>This can be computed as follows:</em></u>
</span>
of 45 =
<span> * 45
= </span>
=
<span>= 9
Therefore, </span>
<span> of 45 is 9

Answer:
x= 60° degree
Step-by-step explanation:
180°-40°= 140°
140= x+ x+ 20
140 -20 =2x
2x = 140 - 20
2x = 120
x = 60°
Percent is parts out of 100 so x%=x/100 so
93%=93/100
