Answer:
Step-by-step explanation:
By geometric mean theorem,
In a triangle ABC,


y² = 60
y = √60
y = 7.75
Similarly, 

x² = 40
x = √40
x = 6.32
Answer:
slope = -5

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
Step-by-step explanation:
Solving like terms
-4x - 7x - 2y -8y
-11x - 10y
