(7) m∠A = 52°
(8) m∠B = 117°
Solution:
(7) Let us first define the supplementary and complementary angles.
Supplementary angles: Two angles are said to be supplementary angles if their sum is add up to 180°
Complementary angles: Two angles are said to be complementary angles if their sum is add up to 90°
Given supplement of 142° = 180° – 142°
= 38°
Complement of ∠A = Supplement of 142°
⇒ Complement of ∠A = 38°
Measure of ∠A = 90° – 38°
= 52°
Hence m∠A = 52°.
(8) Given complement of 27° = 90° – 27°
= 63°
Supplement of ∠B = Complement of 27°
⇒ Supplement of ∠B = 63°
Measure of ∠B = 180° – 63°
= 117°
Hence m∠B = 117°.
Answer: perimeter = 302m
area = 5544m^2
Step-by-step explanation:
perimeter = 2(l + b)
= 2(63 + 88)
= 2 x 151
= 302 m
Area = l x b
= 88 x 63
= 5544 m^2
Hope it helped u,
pls mark as the brainliest

The slope is 5/1 and the y-intercept is -3
I think the first one is 4 dollars
Because 30 divided by 4
