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
Answer:
30x + 30y +30
Step-by-step explanation:
Answer:
Step-by-step explanation:
x - 3y -15
x = -3
Two squares root. Because 3 * 3 = 9 and -3 * -3 = 9.
Answer:
A is the correct answer.
Step-by-step explanation:
First do 6 times 6 and then do 36 times 3.14 to get 113.04.
Then do 4 times 4 to get 16 times 3.14 for 50.24
Last do 113 minus 50 for 63 squared.
