Question

practice with trigonometric ratios sp 26
true or false.
$cos(a) = \frac{37}{35}$
$circ$ true
$circ$ false

Explanation:

Step1: Recall cosine definition

For angle $A$ in right triangle, $\cos(A)=\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

Step2: Identify sides for $\cos(A)$

Adjacent to $A$: $35$, Hypotenuse: $37$

Step3: Calculate $\cos(A)$

$\cos(A)=\frac{35}{37}$

Step4: Compare with given value

Given $\cos(A)=\frac{37}{35}$, which does not match $\frac{35}{37}$

Answer:

False
