Answer:
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC = 
<BCA = 
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB = 
= 
=
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) =
ii. tan(C) =
iii. sin(B) =
Answer: you stupid
Step-by-step explanation:
Because your cheating lol
note the greater than or equal sign: ≥
4 is greater than or equal to c: 4 ≥ c
4 ≥ c is your answer
hope this helps
out of these, it would be 4x - 4 * 2
Answer:
-5.7
Step-by-step explanation:
OUR EQUATION IS A QUADRATIC EQUATION
Let Δ be our dicriminant :
- a= 1
- b= 5
- c= -4
- Δ= 5²-4*1*(-4) =25 +16 =41≥0
- so we have two solutions x and y
- x= (-5-√41)/2 = -5.7
