The answer is 110 degrees. The reason is hard to put into simple language.
If the central angle and the acute angle hitting the circumference share the same end points, then the central angle is double the arc whose vertex is on the circumference.
Read that sentence a couple of times. I don't know how to make it simpler.
The arc angle and the central angle both have B and C as their end points.
The arc angle is on the circumference of the circle. The vertex (A) of BAC is on the circumference. If mine is the only answer, wait a few days before awarding a Brainliest. A thanks will do.

Answer:
71 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. If we take that total 180 and subtract 38, we get 142 degrees. If we divide that by two, because the angles are the same, we get 71 degrees. Therefore x=71

Answer:
v² - 6su²v - 7s²[tex]u^{4}[/tex]
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
= v(v + su²) - 7su²(v + su²) ← distribute both parenthesis
= v² + su²v - 7su²v - 7s²[tex]u^{4}[/tex] ← collect like terms
= v² - 6su²v - 7s²[tex]u^{4}[/tex]

first number by 12, find the three
numbers.
Answers
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

3x=-5y-3
*x=5,y=-2
*x=4,y=-3
*x=-5,y=2
*x=4,y=3
please answer step by step
Answers
Answer: x=4 and y=-3
Step-by-step explanation:
To use elimination to solve system of equations, you want to make sure the equations are first in standard form.
2x+4y=-4
3x+5y=-3
We want to make sure either the x or the y are equal so we can eliminate them. Let's eliminate x.
2x+4y=-4 [multiply equation by 3]
3x+5y=-3 [multiply equation by 2]
6x+12y=-12
6x+10y=-6
We can now subtract the equations.
2y=-6 [divide both sides by 2]
y=-3
Now that we know y=-3, we can plug it into an equation to solve for x.
2x+4y=-4 [plug in y=-3]
2x+4(-3)=-4 [multiply]
2x-12=-4 [add both sides by 12]
2x=8 [divide both sides by 2]
x=4
The final answer is x=4 and y=-3.

A metallurgist wants to make 130 grams of an alloy that is to be 20% copper. She has samples that are 14% copper and 22% copper. How many grams of the sample that contains 14% should she use?
Answers
Answer:
She should use 32.5 g of the sample that contains 14%
Step-by-step explanation:
Here, we want to know the number of grams of the sample that contains 14% copper that should be used
let the number of grams that contains 14% copper to be used be x
Then the number of grams of 22% will be 130-x
Thus, mathematically;
0.14(x) + 0.22(130-x) = 0.2(130)
0.14x + 28.6 - 0.22x = 26
0.22x - 0.14x = 28.6 - 26
0.08x = 2.6
x = 26/0.08
x = 32.5
