The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
Area of a triangle = 1/2 x base x height
--------------------------------------
Find Height :
--------------------------------------
3.75 = 1/2 x 2.5 x height
3.75 = 1.25 x height
height = 3.75 ÷ 1.25
height = 3 meters
----------------------------------------------------------------------------
Answer: The height is 3 meters.
----------------------------------------------------------------------------
I think you are missing part of the problem. If you had another equation or a value for x you could solve it.
21 should be the right answer
