Answer:

1. x = 4

2. x = -6

Step-by-step explanation:

1. 5x + 3 = 23 subtract 3 from both sides

- 3 -3

--------------------

5x = 20 divide 5 from both sides

-------- -------

5 5

x = 4

2. 42 = 18 - 4x subtract 18 to both sides

- 18 - 18

---------------------

24 = 4x divide 4 from both sides

----- ------

Which equation can be solved to find one of the missing side lengths in the triangle?aB60512 unitsАCOS(60°) =22 믕cos(60°) = 12Su

Mekhanik [1.2K]

In a right rectangle, we have:

$\sin \alpha=\frac{opposite}{hypotenuse}$ $\cos \alpha=\frac{\text{adjacent}}{hypotenuse}$

For your exercice, hypotenuse=12

The exercise also inform the angle 60°, then:

$\sin \text{ 60}=\frac{\text{opposite}}{\text{hypotenuse}}=\frac{b}{12}$ $\cos 60=\frac{adjacent}{\text{hypotenuse}}=\frac{a}{12}$
