Please help me... I don't understand why I got it wrong(
Answers
You did the first step correctly ... even admirably !
You zeroed in on finding 'x' with laser-like precision, and
you knocked it out of the park.
Then, from there ... you fell off the deep end.
There's no reason that (3x + 18) has to be equal to 2(y+6).
In fact, they add up to 180°, so you could have used that
and solved for 'y'.
BUT ... (5x + 2) and 2(y+6) are "vertical angles", and THEY
are equal.
So 2 (y+6) = 5x + 2
2 (y+6) = 102
(y+6) = 51
y = 45 .
But the angle 3x+18 is not equal to the angle with the y variable.
They are supplementary angles (equal 180) but are not necessarily equal.
The angle that equals 2(y+6) is the angle opposite to it, 5x+2 (Vertical angle theorem).
So you should have substituted 20 into 5x+2

Answer: Choice C
angle HDG = angle HFE
==========================================================
Explanation:
We have the statement given to us. Note that "H" is in the middle for both sequences of three letters. For DHG, start at H and move back one space to get to D. Move back another unit to wrap around to G. So the new sequence is HDG which forms the first angle.
Follow the same pattern but for FHE now. Start at H, move backward one spot to F, then move back again to wrap around to E. We have HFE
This shows angle HDG pairs up with angle HFE. The corresponding angles are congruent due to CPCTC
CPCTC = corresponding parts of congruent triangles are congruent
Notice how angles HDG and HFE are alternate interior angles, which lead to showing DG is parallel to EF.

Answer: 95cm^2
Step-by-step explanation:
Make smaller shapes then add all the areas up together at the end.
6*4 = 24cm^2
3*2 = 6cm^2
For the base of the triangle:
10+3 = 13cm^2
Area of a triangle = (b*h)/2
(13*10)/2 = 65cm^2
65cm^2 + 13cm^2 + 24cm^2 = 95cm^2
