Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

Is 33 a prime number? Explain why or why not
viva [34]

Answer:

No

Step-by-step explanation:

It is not a prime number because it is divisible by 1, 3, 11 and itself, 33.

If it were just 33 and 1, it would be prime, but it has those extra factors

there are a total of 100 balloons.if the ratio of yellow balloons to blue balloons is 8 to 12,how many of them are yellow?
IrinaK [193]
The ratio of yellow balloons to blue balloons is 8:12
Then there are 100 balloons. Making the equation, we are able to have:
8X + 12X = 1000
20x = 1000
X = 50.

Yellow balloons = 8x = 8 * 50 = 400 yellow balloons
Blue balloons = 12X = 12 * 50 = 600 blue balloons

So there are  400 yellows balloons.

If you cut away a triangle of area 59 cm² from a square, the remaining area will be 85 cm². Find the length of the side of the s
siniylev [52]
So the square was fine, then the triangle decided to go for a hike.

now, if the triangle when it took off, it took 59 cm², and the square was left all by its lonesome with only 85 cm², that means with the triangle in it, the square is then 59 + 85 cm², or 144 cm².

\bf \textit{area of a square}\\\\
A=s^2\qquad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
A=144
\end{cases}\implies 144=s^2
\\\\\\
\sqrt{144}=s
\implies 12=s

At the movie theater there are 40 girls and 60 boys seeing a movie. What is the ratio of girls to boys in lowest terms?
pogonyaev
I believe it would be 2:3. 

A 40:60 ratio could be simplified down to a 4:6 ratio which could then be simplified further to a 2:3 ratio.
