(a) The measure of the indicated angle for figure 1 is 48⁰.

(b) The measure of the indicated angle for figure 2 is 42⁰.

<h3>Measure of the indicated angle</h3>

The measure of the indicated angles can be calculated as follows;

<h3>Figure 1</h3>

sinθ = opp/hypo

sinθ = 72/97

sinθ = 0.7423

θ = sin⁻¹(0.7423)

θ = 47.9⁰ ≈ 48⁰

<h3>Figure 2</h3>

sinθ = 65/97

sinθ = 0.6701

θ = sin⁻¹(0.6701)

θ = 42.1⁰ ≈ 42⁰

Which polynomials are in standard form?
Pavlova-9 [17]

Answer:

3z - 1

-5p^{5} + 2p^{2} -3p + 1

Step-by-step explanation:

In a standard form of a polynomial, the value in the power of the variable reduces from left to right.

Therefore, 3z - 1 polynomial is in standard form since the z term comes to the left of the constant term.

Again, -5p^{5} + 2p^{2} -3p + 1 polynomial is also in standard form since the power of p reduces from left to right. (Answer)
