Answer:
x = 70
Step-by-step explanation:
180 - 112 = 68
2x + 2x + 12 + 68 = 360
4x + 80 = 360
4x = 360 - 80
4x = 280
x = 280/4
x = 70
2x = 2*70 = 140
2x + 12 = 2*70 + 12 = 152
180 - 140 = 40
112 + 40 = 152
180 - 152 = 28
112 + 28 = 140
The whole circle (in terms of area) is 360 degrees.
Area of Sector = (angle / 360) * Area of the entire circle
Area of Sector = (45 / 360) * 80 in^2
Area of sector = (1/8) * 80 in^2
Area of sector = 10 in^2
Answer:
x-intercept(s):
(−8,0)
y-intercept(s):
(0,6)
Step-by-step explanation:
B. The equation can become −2(4x − 1) = 12 by applying the addition property of equality because we have: <span>−2(4x − 1) − 7 = 5 / + 7 <=> -2(4x-1) = 12;</span>
This is a simple formula:(a-b)*(a+b)= a^2-b^2
And it goes like this for your example: (a-1)*(a+1)=a*a+a-a-1*1=a^2-1^2=a^2-1
