Answer:

Step-by-step explanation:

The formula for solving for sin is opposite side/hypotenuse.

The opposite side of <A is BC (28 units) and the hypotenuse is AB (53 units).

sin A = 28/53

A = sin^-1(28/53) --> To remove the sin, you have to multiply the inverse of sin on both sides.

A ≈ 41

Hope this helped! <3

Answer:

The value of x = -13

Step-by-step explanation:

Given the expression

$\frac{0.2x+1}{2}=-0.8$

Multiply both sides by 2

$\frac{2\left(0.2x+1\right)}{2}=2\left(-0.8\right)$

simplify

$0.2x+1=-1.6$

Subtract 1 from both sides

$0.2x+1-1=-1.6-1$

Simplify

$0.2x=-2.6$

Divide both sides by 0.2

$\frac{0.2x}{0.2}=\frac{-2.6}{0.2}$

Simplify

$x=-13$

Therefore, the value of x = -13
