Answer:
x = 24 inches
Step-by-step explanation:
We can use similar triangles and proportions to solve. Put the side of the small triangle over the side of the large triangle
5 8
---------- = -----------------
15 x
Using cross products
5x = 15*8
5x = 120
Divide each side by 5
5x/5 = 120/5
x = 24
Alternate interior angles are congruent...they are equal. So lets set them equal and solve for x
3x + 17 = x + 53
3x - x = 53 - 17
2x = 36
x = 36/2
x = 18
For this question, you can substitute in all the values for the variables.
-c + b - a
= -(5) + (-4.1) - (-2)
= -5 - 4.1 + 2
= -9.1 + 2
= -7.1
Hope this helps! :)
I think you want us to draw a <span>two-dimensional shape that had 8 angles total correct? Well here's what I think:
Octagon:
</span>
Answer:
m∠B = 141°
Step-by-step explanation:
sides of polygon (n) = 7
sum of angles of polygon = {(n - 2) * 180°}
= {(7 -2)*180°}
= 5* 180°
= 900°
Now,
m∠B = 900° - 148° - 142° - 130° - 129° - 120° - 90°
m∠B = 141°
