Question

find the measure of x y z in the figure where is 11 BC​

Answer 1

Step-by-step explanation:

x = 180-75-45 = 180-120 = 60°

y = 75°

z = 45°

Answer 2

Answer:

x = 60

y = 75

z = 45

Step-by-step explanation:

By rule of straight lines, we get

75 + 45 + x = 180

Simplifying we get

120 + x = 180

We subtract both sides by 120 to get

x = 60

Also, (if you know trigonometry you will understand this) z must equal 45 as seen in the angle. So, we get

60 + 45 + y = 180

We simplify to get

105 + y = 180

We subtract both sides by 105 to get

y = 75

We see that y and z equal 75 and 45 respectively which is the same as the angles adjacent to x. This is no coincidence, this is a rule in trigonometry.
