Answer: d = ±10
<u>Step-by-step explanation:</u>
169 = +
169 = (12)² +
169 = 144 +
25 =
100 = d²
√100 = √d²
±10 = d

Step-by-step explanation:
Answer:
x = 15
Explanation:
First, add both equations on one side, and set it equal to 180° because it's supplementary:
2x + 8 + 8x + 22 = 180
combine like terms:
10x + 30 = 180
subtract 30 on both sides of the equation and you end up with:
10x = 150
divide both sides by 10 and you get:
x = 15
Answer:
x = 20
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
