Answer:
x = -5
Step-by-step explanation:
Angles "50" and "x+55" are alternate interior angles which means that they are the same.
So 50 = x + 55
That leaves you with x = -5
Yes because an integer is a whole number
3 3/4 inches are equivalent to 3.75 inches:3 3/4 = 3.75. Divide 45 inches by 3.75 to see how many boards are needed: 45 / 3.75 = 12. To check: 3.75 x 12 = 45 inches. So, 12 boards are needed.
Answer:
The answer is 100*
Step-by-step explanation:
The three measures of the angles add up to make a strait line (180*)
Subtract the value of the two given angles from the total of 180 to get the difference
180 (total) - 50 (m<A) - 30 (m<B) = 100 (Answer)
