Answer:
∠ 1 = 110°, ∠ 2 = 70°
Step-by-step explanation:
∠ 1 and 110° are vertical angles and are congruent, thus
∠ 1 = 110°
∠ 1 and ∠ 2 are same- side interior angles and supplementary, sum to 180°
∠ 1 + ∠ 2 = 180°
110° + ∠ 2 = 180° ( subtract 110° from both sides )
∠ 2 = 70°
Answer:
Area of shaded region = 422 cm²
Step-by-step explanation:
Area of rectangle = length × breadth
= 3cm × 10cm
= 30cm²
Area of circle = πr²
= 3.14 × 12²
= 3.14 × 12cm × 12cm
= 452.16 cm²
Area of shaded region = Area of circle - Area of rectangle
= (452.16 - 30) cm²
= 422 cm²
