Answer:
y=60° b=60°
Step-by-step explanation:
the sum of all degrees of interior triangle is 180
in the first one, 30° and 90° have been given.(that small square represent 90°)
so 180°-90°-30°=60°
in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
Answer:

Answer:
That is a positive slope because it's going upward
Step-by-step explanation:
Answer:
x is approximately 10.772
Step-by-step explanation:

To solve for x, we convert this log form to exponential form
If 

to convert it into exponential form we make log alone
Divide by 3 on both sides


Then divide by 2 on both sides
so x= 10.772
