Question

64 41 Solve for <1. « 1 = [?] 720 35°

Answer 1

Answer:

$\displaystyle \angle1 = {73}^{ \circ}$

Step-by-step 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

Step-by-step explanation:

Answer:

Solution given:

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

<1=180-107

<1=73 °
