<span>Complementary angles by definition sum up to 90 degrees.
Let x = measure of angle2.
It's given that angle1 = x + 54
Since complementary, we know (x+54)+x = 90
2x+54=90
2x=36
x=18.
So angle2 measures 18 degrees and angle1 is 18 degrees+54 degrees, or 72 degrees. 72+18 = 90 as expected for complementary angles.</span>
Answer:
278°
Step-by-step explanation:
m arc BAC = 360 -(2×41)
= 360 - 82 = 278°
Answer: 25kg
Step-by-step explanation:
18 + 29 = 47
72 - 47 = 25
She got 25kg of bananas.
Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees, so no.
