Answer: 11.375°

Step-by-step explanation:

55 + (4x + 17) + (4x + 17) = 180°    Set up equation

4x + 4x + 55 + 17 + 17 = 180°    Commutative Property of Addition

8x + 89 = 180°    Combine like terms

8x = 91°    Subtract 89 from both sides

x = 11.375°   Divide both sides by 8

Not entirely sure about this one; you might have to round the answer.

Can some one explain in an easy way pls

What needs to be done first is to add up females and males that have passed.

42 + 14 = 56

so out of 56 students who passed 42 females passed 42/56 = 3/4 = 0.75

out of 56 students who passed, 14 males passed which turns into 14/56 = 1/4 = 0.25

check work; 0.75 + 0.25 = 1.00

NOW WE ARE DOING FAILS.

15 + 5 = 20

so out of 20 students who failed, 15 females failed so it turns into 15/20 = 3/4 = 0.75

out of 20 students who failed, 5 males failed. 5/20 = 1/4 = 0.25

check work; 0.75 + 0.25 = 1.00

i hope this helped! :)
