gavmur [86]

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.

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tan∅ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle = 35°

Opposite Leg = 3

Adjacent Leg = <em>x</em>

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [tangent]:                    tan35° = 3/x
  2. Multiply <em>x</em>:                                     xtan35° = 3
  3. Isolate <em>x</em>:                                       x = 3/tan35°
  4. Evaluate:                                       x = 4.28444
  5. Round:                                          x ≈ 4.3
