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:
4x - 7
Step-by-step explanation:
We can simplify this expression by subtracting the binomial (a bracket with two terms) and collecting like terms (numbers with the same variable).
When subtracting a binomial, are actually multiplying each term in the binomial by negative one.
7x -(7 + 3x)
= 7x -1(7 + 3x) Distribute -1 to each of the numbers
= 7x + (7*(-1) + 3x*(-1)) Multiply
= 7x + (-7 - 3x) Get rid of the brackets.
= 7x - 7 - 3x Combine like terms
= 4x - 7 Simplified expression
