To find a missing length when you have an area and another length you divide the area by the known length
23 4/5 divided by 2 4/5= 8 1/2
Your answer should be 57 .7 I think its right
Answer:
m∠2 = 56°
Step-by-step explanation:
Given;
m∠1 = 10x + 4 and m∠2 = 5x - 4
Angles 1 and 2 are supplementary angles meaning that they add up to 180°
i.e,
(10x + 4) + (5x - 4) = 180°
10x + 5x + 4 - 4 = 180°
15x = 180°
x = 180/15 = 12
m∠2 = 5(12)° - 4° = 60° - 4° = 56°
The correct numbers are a. c. e. and f. The rest are incorrect. Hope this helped
