Answer:
< FAD and <DAH make 90 degrees so they are complementary
<EAC and CAH make a straight line so they are supplementary
Step-by-step explanation:
Complementary angles add to 90 degrees
< FAD and <DAH make 90 degrees so they are complementary
Supplementary angles add to 180 degrees ( a straight line)
<EAC and CAH make a straight line so they are supplementary
Answer: 20
Step-by-step explanation:
18/20 %90
The sum<span> of the measures of the interior angles of any </span>quadrilateral<span> can be found by breaking the </span>quadrilateral<span> into two triangles. Since the measure of the interior angles of any triangle equals 180 degrees, each of the two triangles will contribute 180 degrees to the total for the </span>quadrilateral<span>.</span>
Answer:
43
Step-by-step explanation:
Substitute x = 3 into the expression, that is
5(3)² - 2 = 5(9) - 2 = 45 - 2 = 43
