Answer:
I think 3 ,4 ,and 5 are to only correct ones
Answer:
m∠P = 29
Step-by-step explanation:
Straight line is 180 so:
56 + x = 180
x = 124
So m∠Q is 124 and a triangle is 180 so now:
124 + 27 + h = 180
151 + h = 180
h = 29
m∠P = 29
Answer:
yes, your score is good for a seventh grader.
keep it up and you can score more.
2 parts.....ratio is 5:3...added = 8.....so one of the parts is 5/8 of the total...5/8x....and the other part is 3/8 of the total...3/8x
the difference is 6...
5/8x - 3/8x = 6
2/8x = 6
x = 6 * 8/2
x = 48/2
x = 24
so the total length is 24
with the longest being : 5/8(24) = 15 <==
and the shortest being : 3/8(24) = 9
perimeter = 20 +20 +24 = 64 feet
area = 12^2 + x^2 = 20^2
144 + x^2 = 400
x^2 = 256
x = sqrt(256) = 16 feet
area = 1/2 x 16 x 24 = 192 square feet
cost = 192 x $2 = $384
