Five times a number plus four times the same number is equal to 360. What is the number?
Answers
Answer:
The number is 40.
Step-by-step explanation:
Let the number be x.
Given the statement: Five times a number plus four times the same number is equal to 360.
"Five times a number" means 5x
"Four times the same number" means 4x
Then, as per the given information we have;
Combine like terms;
9x = 360
Divide both sides by 9 we get;
x = 40
Therefore, the number is, 40.
4x40=160
200+160=360

Answer:
A
Step-by-step explanation:
Using the cofunction identity
cos(90 - x) = sinx , or
sin(angle) = cos(complement of angle)
x and z are complementary angles , x + z = 90 , then
sinz = cosx =
Final answer:
In right triangle XYZ, if X and Z are complementary and cos(X) is 11, sin(Z) should be 11 as well. Nevertheless, the cosine of an angle in a standard triangle can't exceed 1 in absolute value, suggesting an error in the provided data.
Explanation:
In a right triangle, if two angles are complementary, their sum equals 90 degrees. In the case of right triangle XYZ, angles X and Z are complementary. This means that angle Z is the complement of angle X. In trigonometry, the sine of an angle is equal to the cosine of its complement.
Therefore, sin(Z) = cos(X).
Given that cos(X) is 11, it follows that sin(Z) is also 11. However, it is essential to point out that the cosine of an angle can't exceed 1 in absolute value in a standard triangle, so there might be a misprint or misunderstanding in the problem. If cos(X) falls within a valid range, then sin(Z) should equal cos(X).
