The answer is 67°.
Since the parallel sides of a trapezoid are called bases, the bases in our given trapezoid are AB and DC. We know that the corresponding pairs of base angles, such as ∠A and ∠D, or ∠B and ∠C, are supplementary, therefore, their angles add up to 180 degrees:
∠A + ∠D = 180°
∠B + ∠C = 180°
Given that m∠A = 113°, we can calculate for the measure of ∠D:
113° + ∠D = 180°
∠D = 180° - 113° = 67°
No whole numbers do as if you look at the factors pairs of 45 none of them add to 17:
1, 45 = 46
3, 15 = 18
5, 9 = 14
The two numbers that add to 17 but multiply to 45 are can be calculated using the quadratic formula and are actually 13.72 and 3.28
Answer:
A ≈ 26.42
Step-by-step explanation:
<em><u>The shape presented is a circle, and the formula for this is:</u></em>
A = π
<em><u>The "</u></em>
<em><u>," is the radius (2.9), so plug this into the formula:</u></em>
A = π
A = π8.41
A ≈ 26.42
