132 in^2
10 x 10 = 100
(1/2)(10+6)(4) = 32
100 + 32 = 132
Answer:
x = 9
Step-by-step explanation:
The angles in red are equivalent and the triangle is isosceles.
This means the sides with lengths 12 and x + 3 are equivalent.
x + 3 = 12
x + 3 - 3 = 12 - 3
x = 9

(-5,-3), Parallel to -3x - 7y = 10, Put in slope-intercept form.
So, we must find the slope of this first.
-3x - 7y = 10
Add 3x to both sides.
-7y = 3x + 10
Divide both sides by -7.
y = -3/7x - 10/7
So, our slope is -3/7.
Remember, if you're looking for a line that is parallel to something, the slopes always stay the same.
*Also remember that slope-intercept form is y = mx+b*
Where m = slope, and b = y-intercept.
We have the points (-5,-3) so our y-intercept is -3.
Our slope is -3/7.
So, simply plug in those values into the slope-intercept form equation! :)
y = mx + b
y = -3/7x - 3

Answer:
Step-by-step explanation:
So angle 3 and 49 are supplementary angels.
So,
m/3 + 49 = 180
m/3 = 180 - 49 = 131
As angel 1 = angel 49
So, the answer will be:
m
