Step-by-step explanation:
Let number be X
Therefore 2.5 of X = 0.75
X = 0.75/2.5
= 0.3
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.
Answer:
assuming <= is less than or equal to
then z/3 is less than or equal to 3
z had to be less than 9
I’m not really sure but I would have to guess 4.5 because all of the other numbers don’t have decimals
