What is the measure of angle A

Mathematics
1 answer:
Arisa [49]3 years ago
8 0

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)

1. Choose the description that matches the inequality. x &lt; 1
marusya05 [52]

Answer:

A line traveling to the left with an open dot on x=1.

Explanation:

The inequality x < 1 basically means "less than 1." On number lines, the further left you go, the smaller the number becomes, and the further right you go, the larger the number becomes. So we know that because it's less or smaller than 1, then the line will be to the left. On the other hand, the inequality does not have a line under it to indicate a "less than or equal to 1," just "less than." Therefore, the dot is open. If there were a line under the inequality, then it would indicate "less than or equal to 1" and the dot would be closed.
