Answer:
A right angle
Step-by-step explanation:
There is a perfect box sitting on the angle.
First you find the area of the square which is 8²=64 than you find the area of a circle using the formula πr² you get 201.06 and divide it by 4 because you only need the quarter and you get 50.26 the last step is to add the two areas together and you get 64+50.26=114.2
Answer cannot be simplified but u would get 7.549
0.99 = 99/100 as a fraction
You must first multiply the terms in parentheses by the numbers outside them. so 4 x (8m-7n) and then 6 x (3n-4m). you will then be left with (32m-28n) +
(18n - 24m). then take away the parentheses and combine like terms to get the answer of 8m-10m.
