Answer:
145°
Step-by-step explanation:
< 6 + <2 = 180° {being linear pair }
70° + < 2 = 180°
< 2 = 180° - 70°
< 2 = 110°
Now
< 4 = < 1 + < 2 (exterior angle of a triangle is equal to the sum of two opposite interior angles)
<4 = 35° + 110°
= 145°
Hope it will help :)
For part a: you just need to find how far the vertex has been moved from the origin, or the point (0,0). As the vertex is at the point (2,-3), it has been translated right 2 horizontally and down 3 vertically.
For part b: you use the info found in part a to create the equation in the form of y=A(x-h)^2+k. In this case, A =1, so you can ignore it. The h value is the horizontal distance the vertex has been moved. Since it has been moved right 2, this part of the equation would be (x-2). I know it seems like it should be plus 2, but values in parentheses come out opposite. For the k value, find the vertical shift, which is down3, or -3.
Now that you have h and k, substitute them back into the equation.
Your final answer for part b is: y=(x-2)^2 -3.
