Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° = =
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x = ≈ 88.2
What is 33% of 400?
<h2>ANSWER AND EXPLANATION</h2>To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.
<h3>DECIMAL</h3>To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.
Now that you have your decimal, multiply by 400:
ANSWER = 132
<h3>FRACTION</h3>To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.
Now that you have your fraction, multiply by 400:
ANSWER = 132
