Answer:
Step-by-step explanation:
area of a circle=πr^2
42=3.14*r^2
42/3.14=r^2
13.37=r^2
=r
3.65=r
3.7=r
therefore radius of a circle is 3.7 ft
Using the point on the graph (4, 1) solve for a
1 = a(4-3)² - 1
2 = a
Answer:
how am i supposed to know
Step-by-step explanation:
- a midline of a trapezoid is always half of the sum of the legs.
so,
2TW = UV + SX
now plug in and solve,
2(14p + 22) = 17p + 4p + 65
28p + 44 = 21p + 65
7p = 21
p = 3

Ok, so x and 67 are supplementary, so you can set up the equation x+67=180.
x=180-67
x=113
Since this is a picture of two lines with a transversal, you know that the angles around the lines are the same. Since x and y are alternate interior angles, they are equal.
So, both x and y equal 113.
