Question

If AB=29 cm and angleA=25 degrees, what is AC to the nearest centimeter?​

Answer 1

Answer:

$AC= 32$

Explanation:

Given

$AB = 29$

$\angle A = 25$

Required

Find AC

I will answer the question with the attached triangle

From the attachment:

$\cos A = \frac{AB}{AC}$

Make AC the subject

$AC= \frac{AB}{\cos A }$

This gives:

$AC= \frac{29}{\cos (25)}$

$AC= \frac{29}{0.9063}$

$AC= 32$
