Answer:
these triangles some is 90°.
72°+2x=90°
2x=90°-72
2x=18
x=18/2
x=9
Answer:
B) 28 cm^2
Step-by-step explanation:
First, find the perimeter 5*4=20
A= ½ 2.75(20) = 27.5
(round to the nearest whole number)
Got it right on the test
__ ← that is a bar representing that it is ongoing.
724/11=65.81
__
x65.81 1)11 cannot go into 7 so u put a x
______ 2)72 goes in 11 6 times so u put 6 next to x
11 | 724.00 3)6 times 11 is 66
-66↓ ↓ ↓ 4)subtract 66 by 72 and get 6
__↓ ↓ ↓ 5)bring down the 4 and put it next to the 6 getting 64.
64 ↓ ↓ 6)64 goes into 11 5 times
-55 ↓ ↓ 7)put the five next to the x6
___↓ ↓ 8)11 times 5 is 55
90 ↓ 9)subtract 55 from 64 and get 9
-88 ↓ 10)bring the decimal up
___ ↓ 11)gring down the zero *remember*:*a zero has unlimited
20 zeros*
-11 12)90 goes into 11 8 times so put a 8 next to x65.
__ 13)11 times 8 is 88
9 14)subtract 90 from 88 and get 2
15)bring down another zero
16)20 goes into 11 1 time so put a one next to x65.8
17)subtract 11 from 20 and get 9
18)it is not ongoing so put a bar over the answer
__
the answer is 65.81 or u can round it, 65.8182
