Answer:
x = 135°
Step-by-step explanation:
The angle x is the same fraction of 360° that the shaded area is of the area of the circle.
The area of a circle is given by the formula ...
A = πr²
For a radius of 12 cm, the area of the circle is ...
A = π(12 cm)² = 144π cm²
Then the measure of angle x is ...
x = (54π cm²)/(144π cm²)×360°
x = 135°
Answer:
x=3
Step-by-step explanation:
5(2)^x=40
Divide each side by 5
5 /5 *(2)^x=40/5
2^x = 8
Rewriting 8 as 2^3
2^x = 2^3
The bases are the same so the exponents are the same
x=3
1) 6-2= a/4
4*4=a
2) x/4= -5+6
x/4=1
x=1*4
3) 9x=-7+7
x=0/9
4) -4=n/5
5*-4=n
5) 5-4=r/20
20*1=r
6) 6*-1= 5+x
-5-6=x
7) v+9=8*3
v=24-9
8)2n+10=-2
2n=-2-10
n=-12/2
9) -your work is wrong because a negative with another negative is an addition-
-9x+1=-80
-9x=-80+(-1)
-9x= -81
x=-81/-9
x=9
10)-6=n/2-10
10-6=n/2
2*4=n
11)-2=2+v/4
-2+(-2)=v/4
4*-4=v
12) 144=-12x-60
204=-12x
204/-12=x
