The angles of a triangle add up to 180 degrees

65 + 3x - 10 + 2x = 180
5x + 55 = 180
5x = 180 - 55
5x = 125
x = 125/5
x = 25 <====

m < B = 3x - 10 = 3(25) - 10 = 75 - 10 = 65 <== B is 65 degrees
m < C = 2x......= 2(25) = 50 <== C is 50

4) -4y= -x + 4<br> 6) y + 3x = 3

wel

Answer:

x=16/13

y= -9/13

Step-by-step explanation:

A: -4y=-x+4

B: y+3x=3

4B: 4y+12x=12

A+4B: 12x= -x+16

-----> 13x=16

x=16/13

-4y= -16/13+4

4y=16/13-4

y=4/13-1= -9/13
