Question

drag each label to the correct location on the figure. not all labels will be used. find the missing angle measurements. 79° 75° 56° 80° 85° 55° 80° 54° 51° 74° 45° 50°

Explanation:

Step1: Recall angle - sum property of triangle

Sum of angles in a triangle is 180°.

Step2: For left - most triangle

$180-(45 + 80)=55^{\circ}$.

Step3: For middle triangle

$180-(54 + 51)=75^{\circ}$.

Step4: For right - most triangle

$180-(74 + 21)=85^{\circ}$ (where $21 = 180-(50 + 109)$ and $109=54 + 55$).

Step5: For bottom - middle angles

One is $180 - 50=130^{\circ}$, other is $180 - 130 = 50^{\circ}$.

Answer:

55°, 75°, 85°
