Help me please I have no clue
Lynna [10]

Answer:

Step-by-step explanation:

You see that there’re angles with 30 and 90 degrees that means that -> 180-(90+30)=60 (measurement of the third angle)

Here you’ll need to use the 30,60,90 degree triangle rule:

The opposite side of 30 degree will be y

30->y

90->2y->12√3 => y=6√3

60->y√3->x => 6√3x√3=6x3=18

To understand the rule better you can check the picture below.Wish it will help you!Good luck!

Solve a-d please i really dont understand
valkas [14]
So i think what you do is if you make a number line like this:

1...2...3...4...5...6...7...8

you have to find out how many numbers are in between 4 and 7, so I would be 3 because there are 3 numbers I between 4-7.

so

a) 3
b) 6
c) 14
d) 8

x=0

y=-3+5(0)

y=-3

(x,y)=(0,3)
