Answer:
x = 25
Step-by-step explanation:
A quadrilateral is inscribed in a circle, so it is a cyclic Quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
3x + 21y = 180°.....(1)
2x + 26y = 180°.....(2)
From equations (1) & (2)
3x + 21 y = 2x + 26y
3x - 2y = 26y - 21y
x = 5y
y = 1/5 x
Plug y = 1/5 x in equation (1)
3x + 21*1/5x = 180
15x + 21x = 180*5
(Multiplying both sides by 5)
36x = 900
x = 900/36
x = 25
1/3 times area of base times height
1/3 x (11x7) x 8
1/3 x 77 x 8
Answer is approximately 205.3

Brainiest if I'm correct, thanks!</h2>
Answer: 7.48
Step-by-step explanation:
Linear graph. take the point at 3 and multiply it by 2
3.74 x 2 = 7.48
Isolate the variable by dividing each side by factors that don’t contain variable.
Answer: x = -2
Hope this helps!
Have a great day!
1) Obtain the slope of the line graphed
The formula for the slope is m = rise / run = Δy / Δx
The origin of the graph is not well defined, but it is shown that the line passes through the points (0,-2) and (2,10)
That means m = (10 - (-2) ) / (2 - 0) = 12 / 2 = 6
2) The slope of any parallel line is the same: 6
3) Use the slope-point equation to find the final equation: (y - b) = m (x - a)
point (a,b) = (2,5)
m = 6
=> y - 5 = 6 (x - 2)
=> y - 5 = 6 x - 12
=> y = 6x - 12 + 5
=> y = 6x - 7
Therefore, the answer is the option D. y = 6x - 7
