yes, since a+b > c for all sides
One option for the final answer is 30 and 22...
I think I would use the second answer that you provided
Answer:
The area of triangle for the given coordinates is 1.5
Step-by-step explanation:
Given coordinates of triangles as
A = (0,0)
B = (3,4)
C = (3,2)
So, The measure of length AB = a =
Or, a =
Or, a =
Or, a =
∴ a = 5 unit
Similarly
The measure of length BC = b =
Or, b =
Or, a =
Or, b =
∴ b = 2 unit
And
So, The measure of length CA = c =
Or, c =
Or, c =
Or, c =
∴ c = unit
Now, area of Triangle written as , from Heron's formula
A =
and s =
I.e s =
Or. s =
So, A =
Or, A =
Or, A = ×
∴ Area of triangle = 1.5
Hence The area of triangle for the given coordinates is 1.5 Answer
Answer:
The larger acute angle is equal to 50.8 degrees.
Step-by-step explanation:
Let's solve for both of the acute angles for the purpose of checking our work at the end with angle A being the top angle and angle B being the one on the base of the triangle (that's not the 90 degrees one). Determining whether to use sin/cos/tan comes from SOH-CAH-TOA.
A = cos^-1 (2√6/2√15)
However, you need to move the radical out of the denominator by multiplying √15 to the numerator and denominator. You should come up with (2√90)/30. So,
A = cos^-1 (2√90/30) = 50.768 degrees.
B = sin^-1 (2√90/30) = 39.231 degrees.
Now, we can check the work by adding the 2 angles to 90 and, if it comes to 180, it's right.
cos^-1 (2√90/30) + sin^-1 (2√90/30) + 90 = 180.

.60 is equal to 6/10
you can simplify that to 3/5
