Since I can really only see number 50, I'll do that one. Since the 3x + 17 and 5x + 3 form a straight line, and you know that a straight line is 180 degrees, you set 3x + 17 and 5x + 3 EQUAL to the 180, set up like this: 3x + 17 + 5x + 3 = 180. Add your like terms on the left side, which gives you 8x + 20 = 180. Then, subtract the 20 from 180, that being 8x = 160. Finally, divide 8 from 160 to get x by itself. Your final answer should be x = 20.

The both equations should equal 180° when combined. So when you add like-terms you get 8x+20=180. X=20°

Triangles 3 and 4 are identical. They are joined in the poster to form a square. Construct a math argument to show why triangles

Bond [772]

Triangles 3 and 4 are isosceles right angles because they have same length.

<h3>How to explain the triangle?</h3>

It should be noted be noted that the square has all right angles equal. The largest angle of the triangle is the right angle m.

Here, the triangles are isosceles right angles as both the legs and the acute angles are congruent.
