Answer:
4 12
3 18
5 20
7 42
5 15
Step-by-step explanation:
all of the above form a proportion
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:
x=(m)(7)(6) or x=m*7*6
Step-by-step explanation:
4 1/2 = 9/2
5/9 x 9/2 = 45/18
