First one is c
second one is b
and third one is c
Let's first find the slope. This is (y_2 - y_1)/(x_2 - x_1), where (x_1, y_1) and (x_2, y_2) are points.
For this problem, our slope is (0 - 2)/(3 - 0) = -2/3.
We can now use the point-slope formula to find the equation of our line:
(y - y_1) = m(x - x_1)
(y - 2) = -2/3(x - 0)
y - 2 = (-2/3)x
y = (-2/3)x + 2
The equation of our line is

.
Vertex angle = x
1 base angle = 1/2x - 8
180-x = (1/2x-8)x2
180-x = x-16
196-x = x
196 = 2x
x=98

Answer:
solution:Here
Given,
Load=800 N
Load distance=2cm
Effort distance=260cm
Effort applied=?
We know that,
Load × Load distance = Effort × Effort distance
or, 800×2 = e × 260
or,1600 = 260e
or,e = 1600/260
Thus, e = <u>6.15</u><u> </u><u>N</u>
<u>Hence</u><u>,</u><u> </u><u>The</u><u> </u><u>effort</u><u> </u><u>applied</u><u> </u><u>=</u><u> </u><u>6.15</u><u> </u><u>N</u>
