There are 180 degrees in a triangle and if two of them are the same we can call them both a:
a + a + b = 180
2a + b = 180
Next, b is 12 degrees less than a so:
a - 12 = b
2a + a - 12 = 180
3a - 12 = 180
Add 12 to both sides
3a = 192
Find a:
a = 192 / 3
a = 64
This means angle 1 and angle 2 are equal to 64 degrees and angle 3 is 52 degrees
To check:
64 + 64 + 52 = 180 degrees
Answer:
-8y = 6
Step-by-step explanation:
-6x+4y = -8
6x -12y = 14
Add the equations
-6x+4y = -8
6x -12y = 14
--------------------
0x -8y = 6
