Given the figure below, find the values of x and z

x = 5 , z = 80

Step-by-step explanation:

(7x 45) and (6x + 70) are adjacent angles on a straight line and sum to 180°

7x + 45 + 6x + 70 = 180 , that is

13x + 115 = 180 ( subtract 115 from both sides )

13x = 65 ( divide both sides by 13 )

x = 5

Then

7x + 45 = 7(5) + 45 = 35 + 45 = 80

z and (7x + 45) are vertically opposite angles and are congruent , so

z = 80

step-by-step explanation:

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
