scale drawing for a backyard is shown below. In the drawing, 3 cm represents 4 cm. Assuming the patio is rectangular, find the area of the real patio.

Lines equal 180°. The line with angles 5 and 7 equals 180°. If angle 7 equals 61°, then angle 5 equals 119° (180° - 61°= 119°).

Angles 5 and 8 are opposite vertical angles, which are always congruent (equal), so angles 5 and 8 both equal 119°.

119° (angle 5) + 119° (angle 8)= 238°

ANSWER: The two angles total 238° (bottom choice).

Hope this helps! :)
