The value of x in each figure is 34°, 17.1° and 75° respectively.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
1) x + 146° = 180° (sum of angles in a straight line)
x = 34°
2) x + 62.9° = 90° (complementary angles)
x = 17.1°
3) x + 105° = 180° (sum of angles in a straight line)
x = 75°
The value of x in each figure is 34°, 17.1° and 75° respectively.
