The ratio of cos Z is cos Z = 3 / 5
<h3>How to find the trigonometric ratios of a right triangle?</h3>
A right triangle has one angle of the triangle as 90 degrees.
The sides of the right triangle can be found using trigonometric ratios.
Therefore,
sin ∅ = opposite / hypotenuse
sin Z = 3 / 5
Using Pythagoras theorem,
c² = a² + b²
5² - 3² = b²
b² = 25 - 9
b² = 16
b = √16
b = 4
Hence,
P + A = 90 degrees (complementary angles)
Therefore,
sin P = cos Z
cos Z = 3 / 5

Answer:
13.5 minutes
Step-by-step explanation:
128 = 3 minutes
128/3 = 1 minute worth of words
42.6 = 1 minute
576/42.6 = 13.5
Answer:
The answer is -48
Step-by-step explanation:
First step is to follow PEMDAS
So we start solving whatever is in the ( )
4^2 is in the ( ) 4^2 = 16 then we multiply
-3 * 16 which is -48

Answer:
(x,y) = (8,7)
Step-by-step explanation:
Solve equation [2] for the variable x
[2] x = y + 15
Plug this in for variable x in equation [1]
[1] (y +15) + y = 1
[1] 2y = -14
Solve equation [1] for the variable y
[1] 2y = - 14
[1] y = - 7 By now we know this much :
x = y+15
y = -7
// Use the y value to solve for x
x = (-7)+15 = 8
Solution :
{x,y} = {8,-7}
Answer:
1040
Step-by-step explanation:
20,000 is how much you have and you would multiply 20,000*5.2% or 20,000*.052 (converting a percent to a decimal.)
