15PTS PLEASE HELP ASAP!!<br> (dont write random answers pls!)
ikadub [295]

Answer:

to find the answer, you need to find the measure of the angle on the other side of the 142. and since it's a straight line, those two angles measures are =to 180 (they're supplementary angles). so the measure of that angle is 38 degrees. to find the measure of the remaining angle, you subtract the angle measures you already know from 180 (because the sum of interior angles in a triangle is 180.) to, the answer is:

180-90-38= 52 degrees or A

Do You Understand?<br>Show Me! Explain how<br>you can use mental math<br>to add 10 to 47.​
Nikitich [7]

Answer:

Well the answer is 57.

Step-by-step explanation:

Okay think about it 10+10 is 20 how do you know this well 1+1=2 and add a zero. So in 10+47 4+1=5 and keep the 7 because the other number is a zero which has no affect on the number unless both numbers are zero.
