If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:
(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).
Now, cross multiply and solve for x:
28x+14=30x
<em>*Subtract 28x from both sides to isolate the variable*</em>
14=2x
<em>*Divide both sides by 2*</em>
7=x

Answer:
the 21st
Step-by-step explanation:
Answer:
x = 57 y = 137
Step-by-step explanation:
x + 43 + 90 = 180
x + 43 + 90 - 90 = 180 - 90
x + 43 = 90
x + 43 - 43 = 90 - 43
x = 57
43 + y = 180
43 + y - 43 = 180 - 43
y = 137
2)
The area of the whole polygon can be found by adding the area of the top square and the bottom rectangle.
Area of square = 1² = 1
Area of rectangle = 3 × 4 = 12
Area of whole polygon = 1 + 12 = 13 inches²
