Answer:
A) CPCTC
Step-by-step explanation:
This part of the proof occurs right after two triangles are proven congruent. One could now conclude and establish that every part of each congruent triangle is congruent, which is what is most likely happening in this scenario.
Answer:
40 cm
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, simplifying gives
4 =
Multiply both sides by (x + 2)
4(x + 2) = 48 ( divide both sides by 4 )
x + 2 = 12 ( subtract 2 from both sides )
x = 10
Hence
width = 4x = 4 × 10 = 40
Is it obvious the 10% of the book's price is the $5 right?
So the book's price is $50.
Angle 4 and 1 are the same. Since angle 4 is 49 degrees so is angle 1. So just plug 49 into the equation for angle 1 and that would look like 49=3x-18. Then solve. Check your work with other equations given.
