Question

Assume a = 7.3, b = 3.5, and ∠a = 70°. Round the length to one decimal place and the angles to the nearest whole number. a. a = 7.3, b = 3.5, ∠a = 70° b. a = 7.3, b = 3.5, ∠a = 7° c. a = 7.3, b = 3.5, ∠a = 71° d. a = 7.3, b = 3.5, ∠a = 69°

Answer 1

The angles are a = 7.3, b = 3.5, ∠a = 70°.

Option (a) is true.

Explanation:

To determine the correct choice, we need to consider the given values of a, b, and ∠a and compare them to the answer choices.

Given:

a = 7.3

b = 3.5

∠a = 70°

Let's compare these values to each of the answer choices:

a. a = 7.3, b = 3.5, ∠a = 70°

This choice matches the given values, so it is a potential candidate.

b. a = 7.3, b = 3.5, ∠a = 7°

The given value of ∠a is 70°, not 7°, so this choice is not correct.

c. a = 7.3, b = 3.5, ∠a = 71°

The given value of ∠a is 70°, not 71°, so this choice is not correct.

d. a = 7.3, b = 3.5, ∠a = 69°

The given value of ∠a is 70°, not 69°, so this choice is not correct.

Based on the comparison, the correct choice is:

a. a = 7.3, b = 3.5, ∠a = 70°

Thus,

Option (a) is true.
