F(5)+G(7) is equal to 1835
F(x) = 1 - x
f(-3) = 1 - (-3)
f(-3) = 4
You would have to find the height.
To do this, you cut the triangle from the upper vertex to the base to create two new triangles.
Then you use the Law of Cosines. You could use the google calculator for this by searching “law of cosines calculator” and inputting the values, but in case of a test, the formula is a^2 = b^2 + c^2 - 2bc cosA
If you could provide an example of a triangle, I will gladly help you with the steps! Hope this helped!
Answer:
Step-by-step explanation:
a straight line has the degree of 180
so you minus 125 from 180 since you already know one angle and get 55 and thats your answer
A long time honestly.
roughly around 4 hours i would think
