Answer:62
Step-by-step explanation:
The answer is 90 because sum is the answer of a addition problem and 40 + 50 is 90
Answer:
m < 1 = 18°
Step-by-step explanation:
If <ABD = 72°, and m < 2 is three times the measure of m < 1, then:
Let < ABC = m < 1 = x
< CBD = m < 2 = 3x
We can set up the following formula, since the sum of the measures of angles < 1 and < 2 is equal to <ABD (72°):
m < 1 + m < 2 = < ABD
x + 3x = 72°
Add like terms:
4x = 72°
Divide both sides by 4 to solve for x:
x = 18
Since x = 18, and m < 1 = x , then m < 1 = 18°.
And since m < 2 = 3x, then m < 2 = 3(18°) = 54°.
Let's check to see whether we derived the correct answers by plugging in the values of m < 1 and m < 2 into the established formula:
m < 1 + m < 2 = < ABD
18° + 54° = 72°
72° = 72° (True statement).

Start by finding the numbers that go into 27. 1, 27...3, 9...I think that's it, right? One of those numbers is a perfect square. The 9. Rewrite the radical like this then:
Now break up the 9 into its perfect square:
Because there are 3 3's you can pull out the root of 9, which is one of those 3's. It will then simplify to
If you had the square root of 8, that would simplify to
4 is a prfect square (2 times 2), so you can pull out a 2, leaving the other 2 under the radical
Hope that makes sense. If you'd like some more examples to help clarify, just ask!
