Please help I’m confused

x=17

Missing angles are 52 and 38.

Step-by-step explanation:

All triangles add up to equal 180 degrees. Using this information we can create an equation to help solve this problem. We are given one of the angles and the other 2 are shown as expressions, so the equation will look like 90+(2x+4)+(3x+1)=180. You can subtract 90 from both sides to simplify the equation to (2x+4)+(3x+1)=90. From here solve for x.

Combine the like terms

Next, subtract 5 from both sides

Then, divide both sides by 5

Then, plug in 17 for x in the expressions to find the missing angles. The top angle is 3(17)+1=52. The bottom angle is 2(17)+4=38.

d. corresponding side lengths in similar triangles are proportional in length.
