Step-by-step explanation:
Area of the original rectangle=7×9 m²
=63m²
Let triangle removed be named as ∆ABC right angle at B, AB=(9-6)m = 3m
BC=(7-2)m =5m
area of ∆ABC= 1/2 ×3×5=7.5m²
area of the shaded region = (63-7.5)m²
= 55.5m²
Answer:
Step-by-step explanation:
Angle QPR is a central angle. When a central angle intercepts an arc of a circle, the arc and the angle have the same measure. So the minor arc, the one that is less than 180 degrees, will have the same measure as the central angle, 170 degrees.
