10x^2 = 50x.....subtract 50x from both sides
10x^2 - 50x = 0...factor
10x(x - 5) = 0
10x = 0
x = 0 <== this one is eliminated because x cannot be zero
x - 5 = 0
x = 5 <== ur answer

Answer:
x and y = 5√2.
Step-by-step explanation:
This is a 45:45:90 triangle so length of x = length of y.
In this triangle the ratio of the sides is 1:1:√2
Finding length of x and y:
1/√2 = x/10
√2x = 10
x = 10/√2
= 10√2/2
= 5√2.
Answer:
Completing the square we get: 
and factoring the term we get: 
Step-by-step explanation:
We need to complete the square for the expression 
For completing the square the expression would be of form 
For given expression we have to add (2)^2 and subtract to make it complete the square.
Now, we have to factor the polynomial using formula 
So, 
Completing the square we get:
and factoring the term we get:
Answer:
x=45°
Step-by-step explanation:
A straight line is 180°. Since we have a 90° angle, and CD is a straight line, 90/2=45
45° is the answer.
