Answer:
The measure of the angles are 34° and 56°
Step-by-step explanation:
Let
x -----> the measure of one angle
y -----> the measure of another angle
we know that
If two angles are complementary, then their sum is equal to 90 degrees
so
x+y=90° -----> equation A
x=0.5y+6 ----> equation B
substitute equation B in equation A and solve for y
0.5y+6+y=90
1.5y=90-6
1.5y=84
y=56°
Find the value of x
x=0.5(56)+6=34°
therefore
The measure of the angles are 34° and 56°
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= ( cross- multiply )
9x = 72 ⇒ x = 8
Also
= ( cross- multiply )
6a = 45 ⇒ a = 7.5
And
= ( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
