Which of the following is the measure of xba if ray ba bisects xby which measures 86 degrees

Mathematics

Stells [14]3 years ago
7 0

Answer:

The measure of angle xba is 43°

Step-by-step explanation:

we know that

If ray ba bisects the angle xby, then the measure of angle xby is divided into two equal angles

see the attached figure to better understand the problem

so

∠xba=∠aby

∠xba+∠aby=∠xby

we have

∠xby=86°

therefore

∠xba=∠xby/2=86°/2=43°

Given the equation below, find the x and y−intercepts by completing the table.What is the problem with using these intercepts to
kvasek [131]

-4x+2y=0

In order to find the x-intercept we need to make y=0

-4x+2(0)=0

Then we isolate the x

-4x=0x=0

x y Ordered Pair type of intercept

0 0 (0,0) x-intercept

Now for the y-intercept we need to make x=0

-4(0)+2y=0

we isolate the y

2y=0

y=0

0 0 (0,0) y-intercept

ANSWER

Colt1911 [192]

Part A:

We see that this pair of equations has 1 solution. On a graph, the solutions of 2 (or more) lines is where the lines intersect. In this case, since these lines intersect 1 time, they have 1 solution.

Part B:

As previously mentioned, the solutions of multiple lines is where the lines intersect. In this case, since they intersect at (4,4), that is the solution.
