Answer:
Step-by-step explanation:
<em>y</em> = 10(- 1) - 3 = <em>- 13</em>
<em>y</em> = 10(0) - 3 = <em>- 3 </em>
<em>y</em> = 10(1) - 3 =<em> 7 </em>
<em>y</em> = 10(5) - 3 = <em>47</em>
Answer:
(2) angle1 = 139, angle2 = 41, angle4 = 41, angle5 = 139, angle6 = 41, angle7 = 139, angle8 = 41
(3) angle1 = 150, angle2 = 30, angle4 = 30, angle5 = 150, angle6 = 30, angle7 = 150, angle8 = 30
Step-by-step explanation:
All angle are either equal to each other or supplementary. I use corresponding angles and vertical angles to prove each of the above.
For number 3, angle 3 and angle 8 are supplementary, so they add up to 180:
8x +70 + (4x - 10) = 180
12x + 60 = 180
12x = 120
x = 10
So if x = 10, then 8x + 70 = 8(10) + 70 = 150
That means all angles are either 150 or 30 for number 3.
