- 4 log₅ x = log₅ 4x - wrong
- 4 log₅ x = log₅ x⁴ - correct
<u>Property to be used </u>
13. y > 2
14. x - 13 < 9;; x < 22
15. x + 86 < 263;; at most 177 pounds

The equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7
<h3>Trigonometry</h3>
From the question, we are to determine which of the given equations can be used to determine the measure of ∠A
In the diagram,
If ∠A is the included angle
Then,
Using<em> SOH CAH TOA</em>
Opposite = 9.4
Adjacent = 6.7
Thus,
tanA = 9.4/6.7
Hence, the equation that can be used to determine the measure of ∠A is tanA = 9.4/6.7. The correct option is A. tanA=9.4/6.7
