Question

Find x using the pictures below please. Will mark branliest for first reply.

Answer 1

Step-by-step explanation:

a) We are going g to use the definition of tangent to find x:

$\tan{18°} = \dfrac{opp}{adj} = \dfrac{15}{x}$

$\Rightarrow x = \dfrac{15}{\tan{18°}} = 46.2$

b) To solve this problem, we are going to use the definition of cosine:

$\cos{70°} = \dfrac{adj}{hyp} = \dfrac{x}{46}$

$\Rightarrow x = 46\cos{70°} = 15.7$
