Answer:

A. 23.6

Step-by-step explanation:

Let the dotted line be y

Then

y/x = sin(50°) ⇒ x = y/sin (50°)

and

29/y = tan (58°) ⇒ y = 29/tan (58°)

So

x = 29/tan (58°)/sin (50°) ≈ 23.6

Correct answer is A. 23.6

What are the solution(s) of -3(x - 1) = x - 5? O-5 and 3 O-3 O1 and 5 O 2

andre [41]

Answer:

x = 2

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

-3(x - 1) = x - 5

Step 2: Solve for x

Distribute -3: -3x + 3 = x - 5
Add 3x to both sides: 3 = 4x - 5
Add 5 to both sides: 8 = 4x
Divide 4 on both sides: 2 = x
Rewrite: x = 2

Step 3: Check

Plug in x to verify it's a solution.

Substitute: -3(2 - 1) = 2 - 5
Subtract: -3(1) = -3
Multiply: -3 = -3

Here we see that -3 does indeed equal -3.

∴ x = 2 is a solution of the equation.
