Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:
H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get
Substituting 'b' in HI and GI we get
Now, by Line Addition Property we get
Substituting 'HI' and 'GI' we get
The value of the variable 'b' is 3 and GH is 9
Answer:
c
Step-by-step explanation:
tye both have the same amount on each side
<h3>
Answer: y = 14</h3>
===================================
Explanation:
The two angles involving x add up to 180 degrees. This is because they are same side interior angles (and because the horizontal lines are parallel)
So,
(angle BCF) + (angle EFC) = 180
(5x - 66) + (2x + 50) = 180
5x - 66 + 2x + 50 = 180
7x - 16 = 180
7x - 16+16 = 180+16 ... add 16 to both sides
7x = 196
7x/7 = 196/7 .... divide both sides by 7
x = 28
This will be used to help find y
Notice how the angles BCF and ACD are vertical angles, therefore they are congruent or the same measure
angle ACD = angle BCF
9y - 52 = 5x - 66
9y - 52 = 5*28 - 66 ..... replace x with 28 (since x = 28)
9y - 52 = 140 - 66
9y - 52 = 74
9y - 52+52 = 74+52 .... add 52 to both sides
9y = 126
9y/9 = 126/9 .... divide both sides by 9
y = 14
