Solve for <1.
« 1 = [?]
720
35°

Answer 1

`\displaystyle \angle1 = {73}^( \circ)`

Explanation:

remember that,

the sum of the interior angles of a triangle is 180°

Thus our equation is

`\displaystyle \angle1 + {72}^( \circ) + {35}^( \circ) = {180}^( \circ)`

simplify addition:

`\displaystyle \angle1 + {107}^( \circ) = {180}^( \circ)`

cancel 107° from both sides:

`\displaystyle \angle1 = {73}^( \circ)`

Answer 2

Explanation:

Answer:

Solution given:

<1+72+35°=180°[ interior angle of a triangle is 180]

<1=180-107

<1=73 °
