Answer:
44
Step-by-step explanation:
if 88 is the right angle degree, that means the acute angle would be half of 88.
88÷2=44
Answer:
let remaining angle in heptagon be a.
a+64=180(linear pair)
a=116
again
x+155+90+163+a+121°=720(sum of interior angle of hexagon is (6-2)×180°)
x+529+a=720
x+116=720-529
x=191-116=75
Answer:
(A) 21
Step-by-step explanation:
5x-15 needs to equal 90 since it is a right angle and 21 makes that true
Answer:
Subtracted 3 from (24+3)
Step-by-step explanation:
3m - 3 + 3
24 - 3 + 3
Since the adding and subtracting go left to right, you can do them in that order.
21+3 = 24.
Now which one gives us 24?
(24+3) - 3
