Answer:
you multiply 10*2=20
and 2+3=5
Step-by-step explanation:
is this right or wrong?
Since the interior angles of a triangle equal 180°, then 180-45=135.
Then you would use 135 to find the remaining two angles: b+3b=135.
4b=135.
Divide to find b. And the plug in whatever b is for the to figure out Angles B and C.
However, I believe the equation it's looking for is: 180=45+b+3b OR 45+4b=180
2 i think. it says one of each doesn't it?
Since we have a horizontal line, y=0 on the x-axis, a vertical line at x=8, and a 45 degree angle line from y=x.
So you essentially have a right triangle with a base that is 8 units wide, and a side that is 8 units high.
Since the area is bh/2, A=8*8/2=32u^2
