Question

42 POINTS PLEASE ANSWER.....The sum of the angles in a triangle is 180 degrees.In a particular triangle the first angle is 18 degrees less than the second angle, and the the third angle is 70 degrees. Write and solve an equation to find the measure of the first angels.​

Answer 1

46

Explanation:

180-70=110

now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.

Answer 2

first angle = 46 and the second angle = 64

Explanation:

(x,x-18,70)

x+x-18+70=180

2x+52=180

2x=180-52

2x=128

x=64

(x+x-18+70) since x is 64 replace;

x=64

x-18= 64-18= 46
