<u>Statement </u> <u>Reason</u>
<u> </u> Given
Subtract 9 from both the sides
<u></u><u> </u> Subtracting same number will not affect equation
Simplification
Multiplying by 5 both the sides
x= 10 By simplifying both the sides
Thus we solved the equation and got x =10 as answer.
Answer:
The answer is the option A
Step-by-step explanation:
see the attached figure with letters to better understand the problem
we know that
The area of the triangle is equal to
where
b is the base
h is the height
In this problem
the formula to calculate the distance between two points is equal to
Find the distance AB
substitute
Find the distance AC
substitute
Find the area of the triangle
we have
substitute
From Left side:
NOTE: sin²θ + cos²θ = 1
Left side = Right side <em>so proof is complete</em>
