What is this and how do i solve
1 answer:
Answer:
<h2>x = 20</h2>
Step-by-step explanation:
The angles 7x° and (x + 20)° are supplementary angles.
Supplementary angles add up to 180°.
Therefore we have the equation:
7x + (x + 20) = 180
7x + x + 20 = 180 <em>subtract 20 from both sides</em>
8x = 160 <em>divide both sides by 8</em>
x = 20

Given:
To find:
Solution:
Substitute .
Subtract 26° from both sides.
Divide by 2 on both sides, we get
Therefore, m∠1 = 35°.
(x + 5) * (x − 5) =
x² - 25
----------------
x * x = x² and 5 * (-5) = -25
Let x and y represent the two numbers. The equation matching the word description is ...
x +4y = 25
