(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

A

Step-by-step explanation:

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

- rearrange, tan60*7 = x, x =

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

y^2 + x^2 = z^2

z =

z = 14

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
