The answer is D, because in the step before that it was proved that the triangles were congruent and CPCTC is used after they are proved congruent.

to solve the question we need to recall one of the most important theorem of circle known as two tangent theorem which states that <u>tangents </u><u>which</u><u> </u><u>meet </u><u>at</u><u> the</u><u> </u><u>same</u><u> </u><u>point</u><u> </u><u>are </u><u>equal</u><u> </u><u> </u>that is being said
since
and it's given that FA and BA are 17 and 29 FB should be
therefore,
once again by two tangent theorem we acquire:
As BC=BH+CH,BC is
- 12+2.5

likewise,AD=AI+DI so,
- 21=17+DI [AD=21(given) and AI=17 (by the theorem)]
thus,
- DI=21-17=

By the theorem we obtain:
Similarly,DC=DG+CH therefore,
- DC=4+2.5=

Now <u>finding</u><u> </u><u>the</u><u> </u><u>Perimeter</u><u> </u><u>of </u><u>ABCD</u>
substitute what we have and got
simplify addition:
hence,
the Perimeter of ABCD is <u>7</u><u>1</u>
Answer:
X+Y=26
X-Y=12
Step-by-step explanation:
fiction books= X
non fiction books= Y
then,
fiction books= X
non fiction books = X-12
but Y= X - 12
from. the statement,
X+Y = 26
X-Y=12
Answer:
2x^2 + 3x + 2
Step-by-step explanation:
Like terms must have exactly the same variables and exponents on the variables.
2x^2 is not a like term to any other term, so it cannot be combined.
3x is not a like term to any other term, so it cannot be combined.
3 and -1 have no variable, so they are like terms and can be combined.
2x^2 + 3 + 3x - 1 =
= 2x^2 + 3x + 3 - 1
= 2x^2 + 3x + 2
