Answer:
B) 10
Step-by-step explanation:
4x+5=45
-5 -5
4x=40
/4 /4
x=10
1/2= 50%
2/5=40% is the answer
I agree with your answer "supplementary". The two angles combine to form 180 degrees, aka a straight angle
Your teacher seemed to have made a typo.
These angles are adjacent which means they share a side and a vertex. Adjacent angles are also supplementary so the measure of the two angles add up to 180 degrees. Since angle 1 is 137 degrees, angle two is 43 degrees. I hope this explanation helps you.
1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.
1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.
The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.
