3- Dada a expressão: = −±√ 2−4 2 . Sendo a = 1, b= –7 e c = 10, os valores numéricos de podem ser: a) –5 e 2 b) –2 e –5 c) 2 e 5 d) 5 e –2

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

two data sets with the same median will not have the same varaibility

step-by-step explanation:
