Please help me whit this question

Answer 1

Answer:

45

Step-by-step explanation:

1. All angles in a triangle add up to 180°, so that means 30° + (2x + 10)° + 50° = 180.

2. With the equation we just formed, let's solve for x.

Step 1: Simplify both sides of the equation.

• $30 + (2x + 10) + 50 = 180$
• $(2x) + (30+10+50) = 180$
• $2x + 90 = 180$

Step 2: Subtract 90 from both sides.

• $2x + 90 - 90 = 180 - 90$
• $2x = 90$

Step 3: Divide both sides by 2.

• $\frac{2x}{2} = \frac{90}{2}$
• $x = 45$

3. Now that we got the value of x, let's test it to see if it really is the correct answer.

• $30 + (2*45+10) + 50 = 180$
• $30 + (90 +10) + 50 = 180$
• $30 + 100 + 50 = 180$
• $130 + 50 =180$
• $180 = 180$

Nice! This means that our answer is correct.

Therefore, x = 45.
