1 answer:

8 0

Cross multiply: 2 * n = 5 * 12

Simplifying 2 * n = 5 * 12

Multiply 5 * 12 2n = 60

Solving 2n = 60

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Divide each side by '2'. n = 30

A = 14.9 cm, b = 14.1 cm and C = 5.7 cm for the triangle shown below.

Kaylis [27]

Answer:

X is 22.5°

Step-by-step explanation:

» Let's assume our diagram is as above, from trigonometric ratio:

${ \tt{ \red{ \sin( \theta) = \frac{opposite}{hypotenuse} }}} \\$

theta is X
opposite is a
hypotenuse is c

${ \tt{ \sin(x) = \frac{a}{c} }} \\ \\ { \tt{ \sin(x) = \frac{5.7}{14.9} }} \\ \\ { \tt{ \sin(x) = 0.3826}} \\ \\ { \tt{x = { \sin }^{ - 1}(0.3826) }} \\ \\ { \boxed{ \tt{x = 22.5 \degree}}}$
