Area of the figure:
Af = a² + 2 a²/4 π = 2.57 a²
Area of the shaded region:
As = 2 a²/4 π = 1.57 a²
x = (1.57 · 100) / 2.57 = 61 % ≈ 60 %
Answer: B) about 60 %
Answer:
0.12 x 15 = 1.8
Step-by-step explanation:
Answer:
100
Step-by-step explanation:
To solve this problem, we have to use the interior angles theorem which states that the sum of all three interior angles of a triangle must sum 180°.
Having said that, we express the following.

Now, we solve for <em>x</em>.

Then, we use this value to find the angle T.

<h2>Therefore, the angle T is equal to 70°.</h2>
