Answer:
The answer is 20
Step-by-step explanation:
In ratio what you do one side you do on the other side 5:4=25:20
5×5=25
4×5=20
These are the important trigonometric relations to base on:
cot (x) = 1/tan(x)
sec(x) = 1/cos(x)
csc(x) = 1/sin(x)
Following these properties, we could simplify the equation and input into the calculator to determine the exact value.
<span>tan40/cot50 = tan40/(1/tan50) = tan40tan50 = 1
</span><span>sec55/csc35 = (1/cos 55)/(1/sin 35) = sin35/cos55 = 1</span>
Answer: the answer would be 1.5 i think.
Step-by-step explanation:
subtract 2 from 0 to get -2 and then divide 3 by 2 to get 1.5.
Hello
<span>an equation for the line in point-slope form and general form is :
y = ax+b a : </span>slope ; the <span>Passing through (x' ; y')
</span>y' = ax'+b
y-y' =a(x-x') and : x' =8 y' = -4
calculate a :
let : y = ax+b .....(D)
....(D') y = (1/5)x+4
.(D) perpendicular to(D') : slope (D) × slope (D') = -1
slope (D') = 1/5
slop(D)×(1/5) = -1
slope (D) = -5
equation for the line : y-y' =a(x-x')
y+4 =(-5) (x-8)
