Answer:
4.84 square inches
Step-by-step explanation:
To first find the missing angle, 180 - (50+47) = 83
Then I used the formula Area = (a x b x sinc) / 2
Plug in side one for a, side two for b, and the angle between for c
Answer:
x = 23 , y = 21
Step-by-step explanation:
-6x + 7y = 9 -- (1)
2x - 2y = 4 -- (2)
(2) x 3 : 6x - 6y = 12 -- (2)'
(1) + (2)' : y = 21 -- (3)
Subtituting (3) into (2),
2x - 42 = 4
2x = 46
x = 23 -- (4)
According (3) and (4),
x = 23 , y = 21

Step-by-step explanation:
First line up the decimals and just subtracted. And that's it.
In a question like this, you want to approach it with the equation "slope intercept form" which is

b = y-intercept
- the point where the line intercepts the y-axis
m = slope
I suggest using Desmos Graphing Calculator, it really helps and shows you a graphed equation. Let me know what you get!
