Question

how do you Find missing angles in triangles using ratios

Answer 1

Step-by-step explanation:

sum of all angles in triangle =180 degree

according to ratio you have to divide it

for example

let the angles of triangle be 2x 3x and 4x respectively

ration is 2:3:4

2x+3x+4x=9x

180÷9=x

20=x

2x=2×20=40degree

3x=3×20=60degree

4x=4×20=80degree
