Answer:
m<BCA+m<BCD=180
Step-by-step explanation:
supplementary means that the angle measures add up to 180°, if you are using the definition of supplementary angles AND you have had a statement saying that two angles are supplementary, ALWAYS follow it with the sum of the measures of those angles equal 180 :)
D. 5x = 45 because you are trying to find x, the number of tickets that must be sold to earn $45.
(9-4) + 3•8 = 29
Explanation
First you need to apply the PEMDAS rule
Parentheses
Exponents
Multiplication
Division
Addition
Subtract
So when solving the problem you first have to solve what’s in Parentheses first. So (9-4) which would equal 5
Next, according to the PEMDAS rule you’d have to do multiplication next. So 3•8 is equal to 24
And finally, the last step is Addition. After you’ve done the Parentheses and Multiplication you have to add up your answers. 5+24 would be 29
Answer= 29

Explanation:
Let say right triangle ABC has A = 90 deg.
=> BC is hypotenuse.
=> BC = AC x BC/AC = AC/(AC/BC) =AC/cosC.
That's the way we've done!
