∠ BAC + ∠ BCA = ∠ CBE

Step-by-step explanation:

See the attached diagram of the triangle.

We know from the property of angles of a triangle, the sum of any two interior angles is always equal to the opposite exterior angle.

Now, ∠ BAC and ∠ BCA are two interior angles of Δ ABC. Therefore, the opposite exterior angle is ∠ CBE.

Hence, ∠ BAC + ∠ BCA = ∠ CBE (Answer)

46.2+112.3

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
