(8x^2 - 3x^3) - (2x^2 - 5x^3)

= 8x^2 - 3x^3 - 2x^2 + 5x^3.

= 8x^2 - 2x^2 + 5x^3 - 3x^3.  Simplify together like terms.

= 6x^2 + 2x^3

A triangle has angles measuring 43° and 62°. What is the measure of the triangle's third angle?
jarptica [38.1K]

Answer:

75 degrees

Step-by-step explanation:

I know the measure of the triangle's third angle is 75 degrees because all the angles of a triangle add up to 180 degrees. So, I did 180-62-43 and got 75. So, in order for this triangle to be true, the third triangle would have to be 75 degrees.

To check: 43 degrees+ 62 degrees+ 75 degrees = 180 degrees.

To test, then E = 24

24 = n * 5

24 = 5n

24/5 = 5n/5

4.8 = 5

Hence, 24 is not a possible output, be use number of membwra cannot be a decimal
