Question

I need help please I don't understand

Answer 1

Answer:

92

Step-by-step explanation:

i will give you process,

x + 48° + 40° = 180° (being angle in a triangle)

or, x + 88° = 180°

or, x = 180° - 88° = 92°

Therefore, x = 92

Copy the same process

Answer 2

Answer:

57.2

Step-by-step explanation:

This is a right triangle so we can use trig ratios.

We are asked to find a side when we know a angle adjacent to that side. And we are given a side opposite of that angle. We can use Tangent to find the side length.

$\tan(40) = \frac{48}{x}$

Take the reciprocal of both sides.

$\frac{1}{ \tan( 40) ) } = \frac{x}{ 48}$

Multiply both sides by 48.

$x = \frac{1}{ \tan(40) } \times 48$

$x = 57.2$
