Answer:
its the second one down my dude. good luck!
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.
Answer:
2 and -5
Step-by-step explanation:
x2 + 3x - 10 = 0
Factors of -10 include, -2 and 5
so now we have to factor
(x-2)(x+5)
so x can equal 2 and -5
1+2=3.
30/3=10
10x1=10
10x2=20
So the answer would be £10:£20
And to check if it’s right £10 + £20= £30
