Answer:
The smaller angle is 45 degrees.
Step-by-step explanation:
Angles measure 180º. If there are two angles and one of them is three times the other, you would just divide 180 by 4.
The equation would look like:
3x + x = 180
First, the x would be added together:
4x = 180
Then, divide both sides by 4:
x = 45
Answer:

Step-by-step explanation:
Given

Find 
To find
, we simply substitute 10 for d and -4 for c in the given expression.
The step is as follows:

Substitute 




The expression cannot be solved any further; so, we can conclude that when d = 10 and c = -4, 
Okay sub equation 2 into equation 1:
so it becomes
x + 3x = 8
4x = 8
x = 2
then 2 + y = 8, therefore y = 6
So the answer is B
Answer:
24x^2(x-2)
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers
Answer:
5
Step-by-step explanation: In total, Trae walked 4 meters north and 3 meters east to get from point $A$ to point $B$. Since 3-4-5 is a Pythagorean triple, the length of $\overline{AB} = \boxed 5$.
