Question #5701

the second angle in a triangle is 4 times as the first angle . the thrid angle 5 times as large as first find all mesures

Expert's answer

let the first angle will be x, then the second will be 4x, and finally the third

will be 5x. we now thet sum of angles in triangle is 180 degrees so x+4x+5x=180

so 10x=180 x=18 so first 18 degrees, second 72 degrees, and the third is 5*18=90

degrees

will be 5x. we now thet sum of angles in triangle is 180 degrees so x+4x+5x=180

so 10x=180 x=18 so first 18 degrees, second 72 degrees, and the third is 5*18=90

degrees
