I believe the answer is A.
Answer:
1 6 15 20 15 6 1
Step-by-step explanation:
To figure this out, we need to look at Pascal's Triangle, which is a tricky little way to find the coefficients for any binomial expression like this! Check the attached photo.
Because this is to the sixth, we need the 6th row, which is <u>1 6 15 20 15 6 1.</u> From this, we know that those numbers are the coefficients!
It would be 4. in the equation y=mx+b, b is the y-intercept.
If you look closely the area where 3x is congruent to the other side of the 90 degree angle with one part as 0.5x + 34
So
3x + 0.5x + 34= 90
x will be 16
So plug it in
0.5(16) + 34= 42 degrees
And
3(16)= 48 degrees
That left half of the circle is 180 degrees and since we know the angle 3x is 48 degrees we subtract it from 180 to get angle AE
180-48
132 degrees is your answer
Answer:

Step-by-step explanation:
We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.
Now, let's write this as an equation:

The missing angle is 180° minus the sum of the other two angles.

Subtract the numbers:
