hey everyone , i would like you please to help me figure out 2 problems they both about figuring out the area of each a triangle ABC and an engineer estimated area of vertical cross section of water flowing under bridge. and there is a model for it .
6.c) Yes I got it!!!
Draw a line AM from A to BC, but perpendicular to BC.
So that B = 75 degrees ; A = 15 degrees ; M1 = 90 degrees
Then we can say that
And then BM is 2,02
With Pythagoras we determine that AM(the height) = 7,534
With pythagoras again, we determine the full length of BC(the base) to be: 7,81
