So a complementary angle is going to equal 90 degrees.
The equation is : x - 10 + 4x - 10 = 90
Then, add together the matching terms : 5x - 20 = 90
Add 20 to both sides : 5x = 110
Then divide both sides by 5 : x = 22
Insert the value 22 into the first equation : (22 - 10) + (4*22 - 10) = 90
Solve : 12 + 78 = 90
Angle UVW = 12 and angle XYZ = 78
Answer:
17b - 2
Step-by-step explanation:
5b - 5 - 12b - 7
Say bye to the 12b, and add 12 to it and the 5.
5b + 12 = 17b
17b - 5 - 7
Add 5 to the 5 and the -7.
-7 + 5 = -2.
Now you have 17b - 2. You can’t go farther, so there’s your answer.
The answer is 0,-9,-18,-27
or just b
