Step-by-step explanation:
here's the solution: -
=》the given pair of angles are corresponding angles, whose measures are equal.
so,
=》x + 5 = 2x - 7
=》2x - x = 7 + 5
=》x = 12
Answer:
looking at this picture i see that the x value is -30 and the y value is 30
and looking at this it looks like the slope is 30°.
Step-by-step explanation:
not sure if this is right because i have a blank memory about things i learned in pre alg.
but if i'm wrong forgive me.
and if i'm right good luck on whatever you are doing.
answer:
a = 15
b = 84
c = 81
steps
a+b+c=180
b=3a+39
c=a+66
a+3a+39+a+66=180
5a + 105 = 180
5a = 75
a = 15
b=3a+39
b=3(15)+39
b=45+39
b=84
c=15+66
c=81
