Answer:
Therefore the measures of the angles are 22.5° and 67.5°.
Step-by-step explanation:
Complementary Angles:
Two angles are Complementary when they add up to 90 degrees.
Example 40° and 50° are Complementary Angles.
If 'x' and 'y' are Complementary Angles the we have

Here,
Let the common multiple be 'x '
Then the the Complementary Angles will be 'x' and '3x'.
....property of Complementary Angles.
Solving the equation we get

Substituting 'x' values we get
x= 22.5°
3x = 3 × 22.5 = 67.5°
Therefore the measures of the angles are 22.5° and 67.5°.
Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of adjacent angle is 180 degree
115 + 8b +1 = 180
8b = 180 -116
b = 8
Similarly
14a - 5 + 115 = 180
14a = 180 -110
14a = 70
a = 14
2. Intersecting diagonals divide each other into equal halves
3d + 5 = 5d + 1
2d = 4
d = 2
Answer:
x = 
Step-by-step explanation:
= 5 ( multiply both sides by x to clear the fraction )
1 = 5x ( divide both sides by 5 )
= x
