Supplementary angles is when 2 angles add up to 180 degrees.
We will name the smaller angle a and the bigger angle b.
therefore:
b - 172.6 = a
a + b = 180
Now we substitute:
a + b = 180
b - 172.6 + b = 180
2b - 172.6 = 180
2b = 352.6
b = 176.3
To find a:
a + b = 180
a + 176.3 = 180
a = 3.7
Therefore,
angle a = 3.7 degrees
angle b = 176.3 degrees.
Hope it helps and have a great day ahead
Because x was *3 you had to y*3 which is
y=6
The answer is 104.
1/4 of 104 is 26, 104 - 26 = 78
78 - 7 = $71
149 will be rounded to 150 so 150×5= 750
Answer:
1550
Step-by-step explanation:
1250-(-300) <-- positive due to two negative
1250+300
1550
