Answer:

27.7°

Step-by-step explanation:

To find m<A, apply trigonometric function.

Reference angle = A

Side length opposite to A = 20

Hypotenuse = 43

Apply SOH, which is:

Sin (A) = \frac{Opp}{Hyp}

Plug in the values

Sin (A) = \frac{20}{43}

A = sin^{-1}(\frac{20}{43})

A ≈ 27.7° (nearest tenth)

<span>                   a⁴(3a² - 2a + 1)

We just have to multiply each term inside the parentheses by  a⁴  .

           a⁴</span><span>(3a²        )  =  3a⁶
 
           a⁴</span><span>(    - 2a    )  =  -2a⁵
 
           a⁴</span><span>(            1)  =  a⁴

Now, just addum up :      3a⁶ - 2a⁵ + a⁴</span>
