I think it’s the number 3 I’m not sure I’m learning this stuff rn I’m getting the hang of it just it’s hard and not hard at the same time
Answer:
101 or 36 degrees
Step-by-step explanation:
If you add up the measures of the arcs it is 158. That means BC is 202 degrees. Divide it by 2 to find the angle. For the second answer, remember the question did not specify if the arcs were major or minor so you can flip them around.
Answer:
-2y(y + 4)
Step-by-step explanation:
-10y^2 - 3y - (5y - 8y^2)
= -10y^2 - 3y - 5y + 8y^2
= -2y^2 - 8y
= -2y(y + 4)
12/6 = 2
9x2= 18
A builder would spent 18$
see diagram
we see we doulbe the 3 to add
3*2=6
6+12=18
6+15=21
thelength and width of the surfface is 18 by 21
P=2(L+W)
P=2(21+18)
P=2(39)
P=78
the perimiter is 78ft
