Answer:
90
Explanation:
they both add to 90 so 15x minus 43 plus 8X plus 18 equals 90 add like terms 23x minus 25 equals 90 at 25 to both sides 23x equals 11 divide both sides by 23x equals 5q St equals 8X plus 8 equal (5) plus 18 equals 40 + 18 = 58. the other one is just 90-58 or 32
rsq= 32 degrees
qst= 58 degrees
