Answer:

Part 1) The measures of the angles are


(260/15)\°


(606/15)\°


(484/15)\°

Part 2) The measure of the angles are


(315/12)\°


(985/12)\°


(860/12)\°

Explanation:

Part 1) we know that


(5x-8)+(6x+10)+(4x+12)=90\°

solve for x


15x+14=90\°


15x=90\°-14\°


x=(76/15)\°

The measure of the angles are


(5(76/15)-8)=(260/15)\°


(6(76/15)+10)=(606/15)\°


(4(76/15)+12)=(484/15)\°

Part 2) we know that


(3x-20)+(5x+5)+(4x+10)=180\°

solve for x


12x-5=180\°


12x=180\°+5\°


x=(185/12)\°

The measure of the angles are


(3(185/12)-20)=(315/12)\°


(5(185/12)+5)=(985/12)\°


(4(185/12)+10)=(860/12)\°
