Okay so the equation would be (4x+7)+(2x+41)=90 Both sides have to add up to 90, and then that would add up to 180 because all right triangles add up to 180. Solve for x: Step 1: Simplify both sides of the equation. 4x+7+2x+41=90 (4x+2x)+(7+41)=90(Combine Like Terms) 6x+48=90 6x+48=90 Step 2: Subtract 48 from both sides. 6x+48−48=90−48 6x=42 Step 3: Divide both sides by 6. 6x/6=42/6 x=7 Then plug 7 into each equation: First equation for angle A would be 4 times 7, then add 7 which is 35. Second equation for angle B would be 2 times 7 plus 41 which is 55. And for angle C it would be 90 because it's the right angle. I hope I could help sweetie.
