They are the options that are clear enough
Given that,
ABC is a right angle triangle, C is the right angle.
To find,
cosB = ?
Solution,
The sum of angle of a triangle is equal to 180 degrees. So,
∠A + ∠B + ∠C = 180°
Put ∠C = 90°
∠A + ∠B + 90° = 180°
∠A + ∠B = 90°
Taking cos with each term.
cosA+cosB = cos (90)
cosA+cosB = 0
cosB=-sinA
Hence, cosB = sinA.
$55,000 - $10,000 = $45,000
$55 - $15 = $40
$45,000 ÷ $40 = 1,125
So, your answer is 1,125
For, future reference, in word problems, highlight the key terms and it may come easier to do them.
Answer:
(x+30) (x+0)
