Find the values of x and y

see below

Step-by-step explanation:

• find x

use tan rule

tan( 60 degrees) = x / 7

tan ( 60 ) x 7 = 12 . 1

x = 12. 1

• find y

you can either use Pythagoras theorem or the sin rule

let's use sin

sin ( 30 ) = 7 / y

y = 14.0

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
