Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle = 
52.5 * 2 = base × 7
105 = base × 7
base = 15
Answer:
6 : 4
Step-by-step explanation:
3 : 2
6 : ?
3 × 2 : 2 ×2
6 : 4
78, because you have to do the inverse operation so 80/2= 40 then 40-1= 39 and 39*3 = 78
Where are the triangles so I can compare to find the triangle congruence?
rechecking this answer with your lecturer. Tq
