Answer:

Step-by-step explanation:
Let the angle between
and 150° be = b°
[ Forming a linear pair of angles]
Solving for
by subtracting both sides by 150.

∴ 
[Angle lying on a straight line add up to 180]
Plugging in 

Solving for
by
subtracting both sides by 80.

then dividing both sides by 2.

Answer:
AC=6
Step-by-step explanation:
You can see that ABC is 4 times bigger that HIJ because of lines AB and HI. HI(with a value of one) had to be multiplied by four to equal AB (a value of 4). Use this same rule to find the side AC.
1.5(the length of HJ) times 4 =6.
