5a)
2x + 94 = 7x + 49 (vertical angles are equal)
2x - 7x = -94 + 49
-5x = -45
x = 9
Answer
9
5b)
4y + 7x + 49 = 180 (supplementary angles, sum = 180)
4y + 7(9) + 49 = 180
4y + 112 = 180
4y = 68
y = 17
Answer
17
6)
x = 6x - 290 (vertical angles are equal)
-5x = -290
x = 58
Answer
58
Answer:
Step-by-step explanation:
<u>Step 1: Set y to 15 and solve</u>
<u />

<em>Add 10 to both sides</em>
<em />

<em>Multiply both sides by 5</em>
<em />

Answer: 
You know that D is 35° cause of the angle next to F. and <E=180-(120+35) so E is 25°
F(x)=[(1/x)-5]+8 °°°°°°°°°°°°
