Answer: 10 x -5 - 2 x 4 = -58
Step-by-step explanation: the z from the 10 z becomes -5 and the x becomes 2 and the y becomes 4 simply just answer it
<u>Q1: Given sin(x+22)° = cos(2x−7)°
</u>
Using the concept of Right triangles and Trigonometric ratios, we can use a formula given as follows :-
If, sin(A) = cos(B). Then we must have A + B = 90 degrees.
We have sin(x+22)° = cos(2x−7)°
Then it must be true that (x+22)° + (2x−7)° = 90 degrees.
(x + 22) + (2x - 7) = 90
3x + 15 = 90
3x + 15 - 15 = 90 - 15
3x = 75
Hence, x = 25 degrees is the final answer.
<u>Q2: Given cos(x) = 1213 and sin(x) = 513. </u>
It says to find ratio of tan(x).
Using the concepts of Trigonometric ratios, We can the formula that relates all three functions i.e. sin(x), cos(x), and tan(x).
tan(x) =
We can plug the given values in the formula.
is the final answer.
The answer is 30
we expect that in every 50 people, 1 will have free admission.
so:
Answer:
Last one: 5x - 3√y + 1
Step-by-step explanation:
8x + √1 - √9y - √9x^2
8x + 1 - 3√y - 3x
5x + 1 - 3√y
5x - 3√y + 1
