Find x. Assume that segments that appear tangent are tangent.
1 answer:
Assuming that CB is tangent, this is just a right triangle with a hypotenuse of 20 and a side of 12 so by the Pythagorean Theorem:
20^2=12^2+x^2
400=144+x^2
x^2=400-144
x^2=256
x=16

Perimeter:
P = 2(W + L)
P = 2(3.5 + 6.5)
P = 2(10)
P = 20 units
Area:
A = WL
A = 3.5 * 6.5
A = 22.75 square units
Answer:
9/8 or 1 1/8
Step-by-step explanation:
9/4 - 9/8
Need a common denominator, multiply 9/4 x 2/2
18/8 - 9/8
Subtract the top numbers
18-9 = 9
The eight stays the same
9/8 or 1 1/8
Y = -0.33x + -5.00 (rounded to the nearest 100)
Is there a plot?? How do I know where each point is??
