How do you convert how do you convert centimeters to inches
balu736 [363]

In order to convert centimeters to inches, you use the following equation:

1 inches = 2.54 cm

If you have to convert, for example, 4 inches, you proceed as follow:

4 inches* (2.54cm/1 inches) = 10.16 cm

That is, you multiply the quantity that you want to convert, by the quotient between 2.54cm and 1 inches.

Can someone help with number 20
enyata [817]

Answer:B: 36°


Step-by-step explanation:

We know that ∆ABC is isoceles, making (angle)<ABC and <BCA congruent because base angles of isoceles triangles are congruent.


Because we have parallel lines, we can look for alternate interior angle pairs. <BCA is congruent to <DAC because they're alternate interior angles.


If <BCA is x then so is <ABC.


Since triangles add up to 180° we can add all of the angles (3x+x+x) and set it equal to 180.

3x+x+x=180

5x=180

x=36


If we were looking for <BAC we would plug that back in and solve, but we're looking for <BCA which is equal to x, therefore m<BCA=36°
