To solve this question we must first find out what is x.
X + x - 4 = 82 degrees
2x - 4 = 82
2x = 86
X = 86/2 = 43.
Here x would be 43 degrees.
We can add up the angles because we know the angle of DAC and the CAB angle add up to give 82 degrees.
Answer:
the slope is 1.33 and the y intercept is 2
Answer:
they got -21 when they were supposted to get +21
and they also got +6x when they were supposted to get -6x
Step-by-step explanation:
that's because -3 and 2x are multiplied together and when you are multiplying negative and positive number you need to get negative result.
when you are multiplying negative with negative number, you will get positive number.
I am pretty sure that the answer is A. because the slopes are reciprocals of each other, and so they are perpendicular
