Angle ABC measures 140°. Angle DBC bisects ∠ABC. Angle EBC bisects ∠DBC. What is the measure of ∠EBC?
1 answer:
Answer:
An angle bisector divides the angle measure into two equal parts. In triangle ABC, B is the point at which the angle lies.
Step-by-step explanation:
Picture segment BD drawn from point B of tri.ABC where it connects to segment AC, creating point D. Now picture E drawn on the newly created segment DC where it connects to point B and down to point C. Here's a drawing to better show this:
It's bisecting the bisected angle ABC. So, 140/2 = 70, and 70/2 = 35.

Given the equations:
5x + y = 4
x - y = 2
Convert the standard from to the slope intercept from
The slope intercept form is : y = mx + c
Where m is the slope and c is y-intercept
So, for the equation 5x + y = 4
the slope intercept form will be:
so, the slope = m = -5
and y-intercept = c = 4
The graph of the line will be as following:
For the second equation: x - y = 2
The slope intercept form is :
The slope of the line = 1
and the y-intercept = -2
The graph of the line will be as following :
