For D:
A triangle always has 180 degrees total. No more, no less. Seeing as though all the sides and angles are the same length, we can just divide 180 by 3, giving us 60. x = 60 degrees.
For E:
We can see there is a 90 degree symbol that surmises both angles. We know the lower angle is 30 degrees, so m must equal 60 degrees.
For G:
Same concept as D, except we gotta do a bit of math. A triangle always has 180 degrees, So we add 50 and 55 together and get 105. Subtract 105 from 180 and we get 75. Therefore, your angle is 75 degrees.
For H:
The 75 degree angle and m are parallel, with the same line passing through it, meaning that m is identical to the other angle. m = 75.
Answer:
14 (exactly 500) or 15 (over 500)
Step-by-step explanation:
We know that Alexis has already bought 50 stamps.
50 + 30 = 80
We need to subtract to see how many stamps she needs.
500 - 80 = 420
We divide by 30 to see about how many weeks it would take.
420 / 30 = 14
We can add 1 more week because she wants to have more than 500 stamps.
hope this helps :)
Answer:
1/3?
Step-by-step explanation:
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:
![+\begin{cases} a+b=64 \\ a-b=42\end{cases} \\ \overline{, \quad2a \quad \ = \ 106} \qquad /:2 \\ a=53](https://tex.z-dn.net/?f=%2B%5Cbegin%7Bcases%7D%20a%2Bb%3D64%20%5C%5C%20a-b%3D42%5Cend%7Bcases%7D%20%5C%5C%20%5Coverline%7B%2C%20%5Cquad2a%20%5Cquad%20%5C%20%3D%20%5C%20106%7D%20%5Cqquad%20%2F%3A2%20%5C%5C%20a%3D53)
When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
