Sum of interior angles in a triangle = 180

So <A + <B + <C = 180

<A = 180 - <B - <C

<A = 180 - 43 - 15

<A = 122

Answer

<A = 122°

Answer:

Area of larger circle = $\pi *r^2=3.14(11^2)=379.94$

Area of smaller circle = $\pi *r^2=3.14(3^2)=28.26$

Probability that it lands in the shaded area (smaller circle):

28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)

<h3>What is probability?</h3>

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

Mr. Larsen's third-grade class has 22 students, 12 girls, and 10 boys.

Two students must be selected at random to be in the fall play.

Then the probability of no boys being chosen will be

Total event = ²²C₂ = 231

Favorable event = ¹²C₂ = 66

Then the probability will be

P = 66 / 231

P = 0.2857

P ≅ 0.29
