Answer:
<em>x</em>=28, <em>y</em>=12
Step-by-step explanation:
The squiggly symbol? This means the shapes/angles are congruent, meaning that if you rotated them around, they would match.
x's match runs along the same line as it's match, and same goes for y's. Imagine rotating around the lower triangle and lining it up with the upper triangle.
Answer:
c/e = e/d
Step-by-step explanation:
These are similar triangles. When you flip the larger one clockwise to enable you to see which sides are corresponding, then you find that:
c corresponds to e'
a corresponds to b
e corresponds to d
Therefore, c/e in the original position = e'/d in the flipped position.
<u>So c/e = e/d</u>
Answer:
148
Step-by-step explanation:
a line (cd) is 180°
cba + and must be 180°
