Answer:
3x - 8 = 2x + 12
(vertical angles)
x = 20
A straight line = 180 degrees,
so 3(20)-8=52
52+128 = 180
so y is 128.
64/100 is easy its just 64 out of 100
collinear points lies in a single line
that means sum of distance between 2 points is equal to distance between end points.
for example if A B and C lies in a line then
AB + BC = AC
here (1,1) , (2,2) and (3, 3) follows the same rule. ao ans is option D
Solution:
<u>Note that:</u>
- Area of circle: πr²
- r = 11 ft.
<u>Substitute the radius in the expression to find the area of the circle.</u>
- (π)(r²)
- => (22/7)(11²)
- => (22/7)(121)
- => 380.29 ft² (Rounded)
Answer:
-625
Step-by-step explanation:
The magnitude gets raised to the power, and the angle gets multiplied by the power:
5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625
