Lets start of with what we know.
• There are two 27 degree angles 27 + 27 = 52 is the sum of the angles.
•There are 360 degrees all around the intersection
So, we can find out the sum of the 2 angles that are unknown by subtracting.
360-52=308
So, if the sum of the unknown 2 angles are 308, we can divide by 2 to find the measure of the unknown angles.
308/2=154
Answer:
a,b and dcbecause it equals 1
Step-by-step explanation:
you have to find something that is gonna divide by itself to get a postive number, so d wont work bc it would be 24 divided by 25
Answer:
The other angle would also measure 89°.
Answer: (7, 20)
Concept:
There are three general ways to solve systems of equations:
- Elimination
- Substitution
- Graphing
Since the question has specific requirements, we are going to use <u>substitution </u>to solve the equations.
Solve:
<u>Given equations</u>
y = 3x - 1
2x + 6 = y
<u>Substitute the y value since both equations has isolated [y]</u>
2x + 6 = 3x - 1
<u>Add 1 on both sides</u>
2x + 6 + 1 = 3x - 1 + 1
2x + 7 = 3x
<u>Subtract 2x on both sides</u>
2x + 7 - 2x = 3x - 2x

<u>Find the value of y</u>
y = 3x - 1
y = 3(7) - 1
y = 21 - 1

Hope this helps!! :)
