Answer:
100 degrees
Step-by-step explanation:
the part next to the 43= 37, (37+43) x 2 = 160
for b and the section below: 360- 160 = 200 ; 200/2 = 100
Find the area of the base:
(1/2)(4)(5) = 10
Then find the area of one of the sides:
(1/2)(4)(10) = 20
There are 3 sides and 1 base therefore:
20(3) + 10(1) = 60 + 10 = 70sqft
Hope this helps :)
Answer:
(4x+7)(4x-7)
Step-by-step explanation:
You can divide 140 by 4 which is 35
so it would be 35 words per minute
and if you want to find out if it works with the 525 word in 15 mintues
you can do 35 ×15 = 525
I used mental math and it took a long time, but I got the answer of 2,499.
