Two numbers in a ratio 5:4 . Their sun is 720.find the bigger number.show your reasoning

1 answer:

6 0

5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400

Two angles are supplementary. One angle has a measure of 44 degrees. What is the measure of the other angle?

xxMikexx [17]

If A and B are supplementary angles, then:
A+B=180º

In this case:
A=44º

44º+B=180º
B=180º-44º=136º

Anser: the measure of the other angle is 136º
