Answer 1

117º

Explanation:

A triangle's interior angles add up to 180º and the angle of a straight line is 180º.

• We can write, 38º+(180º-101º)+(180º-xº)=180º
• Subtract, 38º+79º+(180º-xº)=180º
• Add, 117º+(180º-xº)=180º
• Subtract, 180º-xº=63º
• Subtract, -xº=-117º
• Convert to positive, xº=117º
