The acute angles of a right triangle are complementary, so
α + β = 90
(5x/3 +20) + (2x/3) + 14) = 90 . . . . . . substitute given values
7x/3 +34 = 90 . . . . . . . . . . . . . . . . . . . collect terms
7x/3 = 56 . . . . . . . . . . . . . . . . . . . . . . . subtract 34
x = (3/7)*56 = 24 . . . . . . . . . . . . . . . . . multiply by 3/7
Then the value of α is ...
α = 5*24/3 +20 = 60
Answer:
D
Step-by-step explanation:
Then you find the intersection and get the bisector without a protractor :)
Total number of marbles = 5 + 8 + 7 = 20
Total number of non-red marbles = 5 + 7 = 12
P(not red) = 12/20 = 3/5
