Answer:
18.0 cm to 1 decimal point.
Step-by-step explanation:
First work out the unknown side (s) of the right triangle using the Pythagoras theorem:
s^2 = 13^2 - 5^2
= 169 - 25 = 144
s = sqrt 144 = 12 cm.
Now consider the other triangle:
s = 12
The missing angle = 180 - 65 - 40 = 75 degrees.
By the Sine Rule:
x / sin 75 = 12 / sin40
x = 12 sin 75 / sin 40
= 18.03

Answer:
1,125 households would have pets in the area.
Step-by-step explanation:
We have 1,500 total households. We also know that 3/4 (or 0.75) of these households have pets. We would multiply 1,500 by 0.75 (which is equal to 3/4), resulting in 1,125. Therefore, 1,125 households would have pets in the area.

Answer: -56 or b.
Step-by-step explanation: -6+(-73)=-79 because the negative number means minus.
-79+(positive)56=-23 because a negative number plus a positive number is adding the positive number meaning you subtract but keep the negative sign
-23+(-33)=-56 because the negative number means minus
I don't know how to explain that is just kind of how it works.
But here's something for the future.
Positive+(Negative) is minus
Positive+Positive is plus (duh)
Negative plus negative is minus (or add but theres a negative sign)
Negative-negative=plus (idk why but its meth)
