Answer:
Alternate-exterior angles theorem.
Step-by-step explanation:
Two parallel lines are cut by a transversal, and if there are a pair of congruent angles that are outside of the parallel lines, and on opposite sides of the transversal, you will have the alternate-exterior angles theorem.
Rectangle
l = 7.2 - 1.7 = 5.5 ft b = 3.4 ft
Semicircle
r = 1.7 ft
Shaded region = area of rectangle + area of semicircle
= l x b + πr²/2
= 5.5 x 3.4 + 3.14 x 1.7 x 1.7 x 1/2
= 18.7 + 4.5373
= 23.2373 ft²
First multiply (-5/6) and (1/6) to get

then you subtract that from (8/9) to get

final answer is
A
Subtract 32 from both sides first, then divide both sides by 9/5
Answer:
A = 60
B = 30
Step-by-step explanation:
Complementary angles add to 90 degrees
A = 2B A is twice the measure of B
A + B =90 Complementary angles add to 90 degrees
Substitute the first equation in for the second
A+B =90
2B+B=90
Combine like terms
3B = 90
Divide by 3
3B/3 = 90/3
B = 30
A = 2B
A = 2*30
A = 60
