Answer:
sin ∅ = 16 /34
cos ∅ = 30 /34
tan ∅ = 16 /30
Step-by-step explanation:
SOH CAH TOA
sin = opp/hyp
cos = adj/hyp
tan = opp/adj
the hypotenuse is always across from the right angle and has the longest side
Answer:
Option (2)
Step-by-step explanation:
Given : y = 
If x = 7i
y = 
By simplifying denominator of the given rational expression,
y = 
y = 
y = 
y =
[Since, i² = (-1)]
y =
y = 
y = 
Therefore, Option (2) is the correct option.
Answer: here u go and can u give me brainliest
Step-by-step explanation:
I'm not quite sure, you should be able to divide the original number by 1
4x + 3y = 54 (1)
3x + 9y = 108 (2)
Multiply (1) by (-3)
-12x - 9y = -162
3x + 9y = 108
---------------------add
-9x = -54
x = 6
plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
y = 10
Answer
(6 , 10)
Hope it helps.
