Answer:
50° and 40°
Step-by-step explanation:
complementary angles sum to 90°
80% = = 0.8
let the 2 angles be x and 0.8x , then
x + 0.8x = 90
1.8x = 90 ( divide both sides by 1.8 )
x = 50
0.8x = 0.8 × 50 = 40
the 2 angles are 50° and 40°
Answer:

Step-by-step explanation:
round the three in the hundreds place up since to the right there is a 9
This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
<span>This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a</span>
Answer:
Question 3:
AC = 3 yd.
m∠B = 37°
m∠C = 53°
Question 4;
GH = 8 km.
m∠H = 62°
m∠I = 28°
Step-by-step explanation:
Question 3:
The length AC
And the angle B
Therefore
And the angle C:
Question 4:
The side GH
The angle I is
Therefore,
And the angle H:
