Answer:
5.0 =x
Step-by-step explanation:
Since this is a right triangle
tan theta = opp side/ adjacent side
tan 50 = x / 4.2
4.2 tan 50 = x
5.005365089 =x
Rounding to the nearest tent
5.0 =x
360 is the total measurement of the angles
Answer:
-3

Answer:
Every percent is a ratio but not all ratios are percents. All ratios can be expressed as percents, decimals, or fractions or in ratio form.
Step-by-step explanation:
A percent is a comparison between a portion of 100 and 100. Because a ratio is a comparison of like quantities, a percent is a ratio. However, ratios can be expressed as decimals, fractions, and in ratio form too. So while every ratio can be a percent, they aren't automatically percents.
The number three (3) when decreased by fifteen (15) is four (4) times its opposite.
In this exercise, you're required to solve for an unknown number by using a variable to represent the number in relation to the known variables (constants) and representing it as an algebraic expression.
Translating the word problem into an algebraic expression, we have;
Rearranging the algebraic expression by (collecting like terms), we have;
Dividing both sides by 5, we have;
<em>x = 3</em>
<em>Therefore, number </em><em>three</em><em> </em><em>(3) </em><em>when </em><em>decreased</em><em> by </em><em>fifteen (15)</em><em> is </em><em>four (4) </em><em>times its </em><em>opposite.</em>
