What is measure of angle R?

1 answer:

7 0

You can use cos, sin or tan for this problem.
I'll use cos.
So we have cos∅=12/13.
We need the angle, so arccos(12/13)=∅. So, just plug that in.

Does anyone know this??

Natalija [7]

Answer:

The y-intercept is 16

Step-by-step explanation:

Here , we want to find the y-intercept

generally, we have the equation of the line as

y = mx + b

where b is the y-intercept and m is the slope

From what we have;

y = 2x + b

To get the slope, we substitute the coordinates of the points (-6,4)

we have this as:

4 = 2(-6) + b

4 = b - 12

b = 4 + 12

b = 16
