Question

Select the true statement about triangle ABC.

Answer 1

Answer:

B

Step-by-step explanation:

cosA = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{12}{13}$

cosC = $\frac{BC}{AC}$ = $\frac{5}{13}$

sinC = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{AC}$ = $\frac{12}{13}$

tanC = $\frac{opposite}{adjacent}$ = $\frac{AB}{BC}$ = $\frac{12}{5}$

Then

cosA = sinC → B
