1 |
Problem |
Find the value of x in the following figure. |
|
2 |
Step |
The sum of complementary angles is |
90° |
3 |
Step |
The given figure, x and 78° are complementary angles. |
|
4 |
Step |
Now,we find the x the value |
x + 78° = 90° |
5 |
Step |
Subtract 78° on both sides |
x + 78° - 78° = 90° - 78° x = 12° |
