Answer:
y intercept 3 and rate of change -2
Step-by-step explanation:
You can determine if a number is rational if it can be represented as a terminating or repeated decimal, but if it can not, then the number is irrational.
First of all, triangles angles add up to 180 degrees.
BCD=120. To find BCA subtract 180-120 to get 60 degrees.
We know what ABC is, it equals 85, so far we have 2 angles.
Lets add them up, 85+60=145
Since the angles must add up to equal 180 we're going to subtract 180-145
Which equals 35, BAC=35 degrees.
