Let x = second angle
let x + 10 = first angle
let 2( (x) + (x+10) ) = third angle.
Since the interior of a triangle equals 180° then,






Inputting the value of x gives us each angle.
second angle = 25°
first angle = x + 10 = 25 + 10 = 35°
third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) )
= 110°
I’m not sure, but I think you divide 360 by each one of those angles.
Answer:
To convert a fraction to a percent, first divide the numerator by the denominator. Then multiply the decimal by 100 . That is, the fraction 48 can be converted to decimal by dividing 4 by 8 . It can be converted to percent by multiplying the decimal by 100
