Answer:

The value of a is 7.4833. The value of A=29.9262^0 and B=60.0735^0.

Step-by-step explanation:

Consider the provided information.

The required figure is shown below:

We need to find the value of a.

Calculate the value of a by using Pythagorean theorem.

a^2+b^2=c^2

a^2+(13)^2=(15)^2

a^2=225-169

a^2=56

a=7.4833

Hence, the value of a is 7.4833.

Now find the value of angle A as shown:

\sin A=\frac{a}{c}

\sin A=\frac{7.4833}{15}

A=sin^{-1}(0.4989)

A=29.9262^0

Find the value of angle B as shown:

\sin B=\frac{b}{c}

\sin B=\frac{13}{15}

B=sin^{-1}(0.8667)

B=60.0735^0

Hence, the value of A=29.9262^0 and B=60.0735^0.

Karo-lina-s [1.5K]

Answer: Fish A: 9 inches ; Fish B: 6 inches

Step-by-step explanation:

This can be turned into a systems of equation, where x equals the length of fish A and y equals the length of fish B:

3x + 2y = 39 → -3x - 2y = -39

3x + 4y = 51 → 3x +4y = 51

Combine: 0 + 2y = 12 → y = 6 inches.

Plug back in: 3x + 2(6) = 39 → 3x = 27 → x = 9 inches.
