BRAINLIEST!!! (Please help)
In the diagram, assume that y= 7. Find x and z.
A)
<= 7 V3; 2= 14
B)
x = 14; 2= 7 V3
©
x= 7 V2; 2 = 14
D)
x = 14; 2= 7V2

Answer 1

Answer:

A

Step-by-step explanation:

- to find x we use tan 60 = x/7

- rearrange, tan60*7 = x, x = $7\sqrt{3}$

- now you have two sides so you can use pythagoras  to find z

y^2 + x^2 = z^2

z = $\sqrt{(7\sqrt{3})^2 + (7)^2 }$

z = 14
