Whats is a 3 step problem that can represent the expression 3x + (-5) = 19

GrogVix [38]

Answer:

$x=8$

Step-by-step explanation:

$3x-5=19\\$

The first step is to add -5 to both sides:

$(3x-5)+5=19+5\\3x=24$

The next step is to divide 3 on both sides:

$\frac{3x}{3} =\frac{24}{3}$

$x=8$

What is the answer to this?

Keith_Richards [23]

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

$z^{2} = 28.31^{2} - 25^{2}$

z = 13.29
