Answer:
212° and 198°
Step-by-step explanation:
Reflex angles are angles greater than 180° and less than 360°
Answer:
Shown in graph.
Step-by-step explanation:
Answer: x=-4, y=-7
Problem:
4x-6y = 26
5x-4y=8
You can use substitution or elimination to solve the problem. I’m going to use elimination.
Multiply by -2 => -8x+12y = -52
Multiply by 3 => 15x- 12y = 24
Add those equations together:
7x=-28
x=-4
Plug that into one of the original equations to get y.
4(-4)-6y=26
-16 - 6y=26
-6y=42
y=-7
Check for the other equation to see if this is true. Which in this case it is. So that’s your answer. x=-4, y=-7
Use the pythagorean theorem A² + B² = C²
A and B are legs and C is the hypotenuse
so- A² + 12² = 24² A² + 144 = 576
-144 -144
A² = 432 then you have to take the square root
of each side
so- A = √432 or aprox. 20.78
<span>Let the first number be x.
Then the second number is 3x.
Then the third number is (x+100).
Sum of the numbers=500
x+3x+(x+100)=500</span>
<span>4x+(x+100)-500=0
</span><span>5x=400</span>
<span>x=80
</span><span>The first number is 80.
The second number is 240.
The third number is 180.
We can check by adding all three of those numbers together: 80+240+180 = 500
