Answer:
A) Sometimes
A ) Sometimes is the correct answer because b) always and c) never is not possible
it cannot be always measured 90 degrees
Area of trapezoid = a + b/2 * h
a = 20, b = 9, h = 21/-16
20+9/2 * (21-16) = 29/2 * 5 = 72.5
The area of the trapezoid = 72.5 in^2
Area of the rectangle = l * w
l = 16, w = 20
16 * 20 = 320
The area of the rectangle: 320 in^2
Answer: the answer is 809
Step-by-step explanation:
Answer:
number 4. 13
because first you do the exponents giving you 8 and then divide which is 2 then you subtract which is 13
Answer:
The measure of angle 1 is 55.
Step-by-step explanation:
The top angle= 75 because of the vertical angle theorem
The right angle= 50 because of the alternate exterior angle theorem
75+50=125
There are 180 degrees in a triangle so the angle has to equal 55
