Question 4 of 10

Mathematics
1 answer:
VARVARA [1.3K]3 years ago
5 0

Answer:

A. x=3

Step-by-step explanation:

4(5x+3)=14x+30

multiply 4 to 5x and multiply 4 yo 3

20x+12=14x+30

move terms

20x-14x=30-12

subtract 20x to 14x and subtract 30 to 12

6x=18

divide both sides by 8

x=3

Which of these sets of angle measures could be the three angles in a triangle?
Lady_Fox [76]

Answer:

Okay so this is simple addition, once you know how to do it. 

The interior angles of a triangle should always add up to 180 Degrees. 

Now that you know this, all you have to do is add the numbers together and see which ones add up to 180 degrees. 

A. - 90+42+58=190

B. - 60+60+60=180

C. - 100+48+42=190

D. - 31+75+70=176

Out of these choices the only one that adds up to 180 is B. So your answer would be B.
