Find the measure of x, then the measure of 6-22<br> 8x + 34<br> R<br> S<br> degrees

grandymaker [24]

Answer:

<em>x = 12 ; m∠R = 130° </em>

Step-by-step explanation:

(6x - 22)° + (8x + 34)° = 180°

6x - 22 + 8x + 34 = 180

14x + 12 = 180

14x = 168

<em>x = 12</em>

m∠R = (8x + 34)° = (96 + 34)° = 130°

<em>m∠R = 130°</em>
