Answer:
Step-by-step explanation:
In the question, we're given . Therefore, the measure of these two angles must be equal.
To find the value of , set these two angles equal to each other:
Add 26 and subtract from both sides:
Divide both sides by 3:
Since was labelled as
, substitute
to find its measure:
You can also substitute into the label of angle D as angle A is congruent to angle D for easier calculations (
).
Answer
a) 2 x + 3 = 13 - 5 x
7 x = 13 -3
7 x = 10
b) 6 + 4 x = 10 x + 26
6 x = 20
c) 6 x + 9 = 13/5 - x
d) 0.6 + 0.4 x = x + 2.6
0.6 x = -2
e) 3(2x + 3) = 13/5 -x
6 x + 9 = 13/5 - x
f) 4 x = -10 x + 20
14 x = 20
g) 15(2x + 3) = 13 - 5x
30 x + 45 = 13 - 5 x
35 x = -32
h)15(2x + 3) + 97 = 110 - 5x
30 x + 45 + 97 = 110 - 5x
35 x = -32
so , the solution of part c, e, g, h is same which is
the solution of part a, f is same which is
