Answer:
A=45
B=110
Step-by-step explanation:
Interior angles of a triangle add up to 180.
So, do 180-25=155.
Then, 155-65=90.
90 divided by 2 is 45.
x=45 so B is 45+65, which is 110.
Answer:
y=7
Step-by-step explanation:
Because it can't be simplified.
There aren't like terms and there isn't fractions.
64.75$ - 3.00$ (delivery) - 7.00$ (tip) = 54.75$
54.75$ divided by 5 = 10.95$
The answer is 10.95$
Answer:
x = -12
Step-by-step explanation:
m∡QRP = 180 - (80 + 43) = 57°
-6x + 51 + 57 = 180
-6x + 108 = 180
-6x = 72
x = -12
