Ok so first 2.4 will have to be changed to 24 which means we multiplied it by ten making it 24/10 since it is tan it is opposite side/ adjacent side so your one of your legs will be 24 and one will be 10. Now we just plug that into the Pythagorean Theorem to find the hypotenuse and we get 26. The area is 24b10/2=120 the area is 120.
Leg a= 24
Leg b= 10
Hypotenuse=26
Area=120
Ignore my awful handwriting but this is what it looks like labeled. I made each unit=2 just so it wouldn't be as large but I hope this helps you :)
Answer:
- y = x -1
- no
Step-by-step explanation:
A graph quickly answers this question.
__
The given points have a horizontal difference of 4-(-1) = 5 and a vertical difference of 3-(-2) = 5, so the slope of the line between them is ...
m = Δy/Δx = 5/5 = 1
The point-slope form of the equation for a line can be written ...
y = m(x -h) +k . . . . . for slope m through point (h, k)
Using the first point and the slope we found, we can write the equation as ...
y = 1(x -(-1)) +(-2)
y = x -1 . . . . . . . . . simplify; this is the equation of the line
__
When we try the third point in this equation, we get ...
y = 3 -1 = 2 ≠ 1 . . . . . the third point is not on the line
