Answer:
A = 6 units ^2
Step-by-step explanation:
Let the base of the triangle be DE. Its length is 3 units
Let the height of the triangle be from DE to point F. That is 4 units ( -3 to 1 is 4 units)
The area of the triangle is
A = 1/2 bh
=1/2 (3)(4)
A = 6 units ^2
Answer:
BC = =12
Step-by-step explanation:
if the triangle is ABC and have part 12
and right angle from B and have an angle 45 then the third angle is 45 too
then we have another part is 12
and the BC = =12
