Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
Answer:
The answer is
.
Step-by-step explanation:
Given:
X/4 + 3/5x.
Now, to find the sum of the rational expressions.

So, to solve it by adding:



Therefore, the answer is
.
Answer:
The amount he needs to pay = $ 650
Step-by-step explanation:
Area= h* (a+b/2)
= 10 * (10+16/2)
= 10 * (26/2)
= 10 * 13 = 130 sq.feet
The amount he needs to pay = 130 * 5 = $ 650
Step-by-step explanation:
The sum of the interior angles of a triangle is equal to 180° so we can write

Solving for y, we get

So the other two angles of the triangle are

and
