The given triangle has two sides marked equal and hence is an isosceles triangle.In isosceles triangle base angles are equal <A=<B=50.
Sum of angles in any triangle is 180 degrees.
<A+<B+<C=180°
50+50+5y+10=180
Adding like terms :
110+5y=180
Subtracting 110 on both sides:
5y=70
Dividing both sides by 5:
y=14.
Answer:
V = 10 x 9 x (1/3)
V = 30 in³
Step-by-step explanation:
The formula for the conditional probability is:

This indicates the probability of event A, given that event B has already occurred.
Here P(A*B) indicates P(A∩B).
Using the given values, in the formula, we can write:
Therefore, option D is the correct answer.
