<span>supplementary angles sum = 180
</span>lets x = measure of angle Y
x + 3x = 180
4x = 180
x = 45
angle Y = 45
angle X = 3 x 45 = 135
answer
Angle X = 135
Answer:
<h3> D){?}
x = 7</h3>
Step-by-step explanation:
x + 3•(+1) = 2•x + 4•(-1)
x + 3 = 2x - 4
-3 -3
x = 2x - 7
-2x -2x
- x = -7
÷(-1) ÷(-1)
x = 7
Answer:
138
Step-by-step explanation:
Hexagon total angle = 720
170+ 277 + 135 = 582
720 - 582 = 138
6adults = 5 babies
12 adults =10 babies
18 adults= 15 babies
24 adults= 20 babies
= 44 total camels
20 babies
