Answer 1

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

• Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

• $(5x)+(23+90-18)=180$
• $5x+95=180$

Step 2: Subtract 95 from both sides.

• $5x+95-95=180-95$
• $5x=85$

Step 3: Divide both sides by 5.

• $5x/5=85/5$
• $x=17$

Step 4: Check if solution is correct.

• $(5*17-18)+23+90=180$
• $67+23+90=180$
• $180=180$

Thus, x = 17.
