Step-by-step explanation:
x+x+10+50=180
2x+60=180
2x=180-60
2x=120
x=120/2
x=60
4 consecutive odd integers...
x, x + 2, x + 4, x + 6
(x) + (x + 2) + (x + 4) + (x + 6) = 232
4x + 12 = 232
4x = 232 - 12
4x = 220
x = 220/4
x = 55
x + 2 = 55 + 2 = 57
x + 4 = 55 + 4 = 59
x + 6 = 55 + 6 = 61
so ur numbers are : 55, 57, 59, 61
Sorry i got nothing for you .. but i'll try to solve it shortly.
1
a and d are supplementary angles, forming a line or adding to 180 degrees, so
d =180 - 120 = 60 degrees
2
f and h are called vertical angles, which are congruent.
h=70 degrees
3
c and f are supplementary. I think they're called consecutive angles.
f = 180 - c = 70 degrees
4
b and c are supplementary, c and g are congruent so
g = 180 - b = 120 degrees
