Question

Find the number that belongsin the green box.[?]109°13°6Round your answer to the nearest tenth.

Answer 1

step 1

Find the measure of the third interior angle of triangle

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

x+109+13=180

solve for x

x=180-122

x=58 degrees

step 2

Applying the law of sines

?/sin(13)=6/sin(58)

solve for ?

?=(6/sin(58))*sin(13)

?=1.6 units
