Answer:The sum of the interior angles of a triangle are equal to 180o. To find the third angle of a triangle when the other two angles are known subtract the number of degrees in the other two angles from 180o.
Example: How many degrees are in the third angle of a triange whose other two angles are 40o and 65o? Answer: 180o - 40o -65o = 75o

Answer:
720 minutes
Step-by-step explanation:
We need to multiply to determine how many minutes in 12 hours in this problem.
Since <u>there are 60 minutes in an hour,</u> multiply 60 by 12:
we get 60 × 12 = 720
So the final result is 720 minutes.
Hope this helps :)
Answer:
y=97
Step-by-step explanation:
1st do 42+55=97 to find
2nd do 180-97=83 to find z so z=83
3rd do then do 180-83=97 sense y and z are supplementary
so therefore the answer is y=97
If brainiest is earned its greatly appreciated
Answer:
10 one-dollar and 4 five-dollar bills.
Step-by-step explanation:
Let x = the number of one-dollar bills and y = number of five-dollar bills.
Then:
x + y = 14
x + 5y = 30 (using the values of the bills)
Subtracting the 2 equations:-
-4y = -16
y = 4
so x + 4 = 14
x = 10.
There are 10 one-dollar bills and 4 five-dollar bills.
