If two angles of a triangle measure 50 degrees and 85 degrees what is the measure of the third angle
Dvinal [7]
I think it's 45 because 50+85=135

*Remember in total the sum of all angles must be equal to 180
So in order to find the missing angle subtract 180-135=45.

45 is the measure of the 3rd angle.

Hope I helped :)

I need help with this one plz! (marking BRAINLIST) :) ​
miskamm [114]

Answer: (a) = 110 degrees, (b) = 8

If I understand the picture correctly, (a) wants you to find the angle K. It first shows us that both J to K, and L to K are equal in length of 11, thus there is no deviation in angle 35 degrees with L (so they both equal each other). Therefore, the angle K will equal 180 degrees subtracted by the sum of J and L, which is 110 degrees.

For (b), it appears that all the angles have the same singular mark at the edges, so all sides will equal 8.

I hope this helped!

2.

distance =  \sqrt{ {( - 4 - 6)}^{2} +  {( - 12 - 8)}^{2}  }  \\  =  \sqrt{500}  \\  = 22.4 \: units

What is the mean, median, mode, and range from this data?
Zinaida [17]

Answer: The mean is 4, median is 4, no mode, range is 4

Step-by-step explanation:

<u>mode</u> is adding all the numbers and subtracting by the total amount of whole numbers

<u>median</u> is putting the numbers in a line ex.( 2, 6, 4, 5, 3) and crossing out left to right until theres one number left

<u>mode</u> is which ever number is repeated the most

<u>range</u> is the biggest number subtracted by the smallest number
