Answer:
Yes
Step-by-step explanation:
If the longest side squared is equal to the sum of the squares on the other 2 sides then they form a right triangle
longest side = 7.5
7.5² = 56.25
2.1² + 7.2² = 4.41 + 51.84 = 56.25
Thus the 3 values form a right triangle.
I guess the mean is always

Answer:
-6 and 7
Step-by-step explanation:
It is useful to look at the factor pairs of -42.
-42 = -1(42) = -2(21) = -3(14) = -6(7)
Sums of these factor pairs are 41, 19, 11, 1.
You want the last pair of factors: -6 and 7.
Answer: 45
Step-by-step explanation:
The total degrees in a circle is 360.
The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.
so 90 + x + 3x = 90 + 4x = total
90 + 4x = 360
4x = 180
x = 45 degrees
