Because the two angles shown are vertical angles, they are equal to each other. Thus, we can write an equation to solve the problem as 4x-15=2x+25. Now solve. Add 15 to both sides. 4x=2x+40 Subtract 2x from both sides. 2x=40 Divide both sides by 2 to isolate x. X=20 Now that we know the value of x, we can use that knowledge to solve for the unknown angles. Substitute 20 for x in both equations. 4(20)-15 80-15 65 2(20)+25 40+25 65 The top and bottom angles are both 65 degrees, and x is 20. Hope this helps!
You forgot to add in your height to your question. To find your area you need to do 8 + 14 and get 22 then you nee to do the height divided by two. If you give me the height of the triangle I can tell you the area.
