Answer:
Angle’s measure is equal to the sum of the measures of ∠BAC and ∠BCA is ∠ CBE.
Step-by-step explanation:
Exterior Angle of a Triangle Property:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Here,
The exterior angle of a triangle = ∠ CBE
For the given angles Sum,
∴ m∠ CBE = m∠ BAC + m∠ BCA
Angle’s measure is equal to the sum of the measures of ∠BAC and ∠BCA is ∠ CBE.

3x + 4y = - 8
The equation of a line in standard form is Ax + By = C
where A is a positive integer and B, C are integers
Express the line in ' slope- intercept form '
y = mx + c → (m is the slope and c is the y-intercept)
here m = - and c = - 2
hence y = - x - 2 → equation in slope- intercept form
multiply all terms by 4
4y = - 3x - 8
add 3x to both sides
3x + 4y = - 8 → in standard form
