Question

List the sides of ΔRST in ascending order
m∠R=2x+11°, m∠S=3x+23°, m∠T=x+42°
pls help

Answer 1

Explanation:

`\angle R+\angle S+ \angle T =180` (angle sum of a triangle is 180°)

`2x+11+3x+23+x+42=180`

`6x+76=180`

`6x=104`

`x=17.667`

`\text{So we get: } \angle R= 46.33,\angle S=76,\angle T=59.667`

In ascending order:

`\angle R= 46.33,\angle T=59.667,\angle S=76`
