14.42 is your distance formula
(1,0) is the midpoint
if you need the forma for distance it is x2-x1 squared + y2-y1 squared then square root it
Answer:
a = 20; b = 2√101
Step-by-step explanation:
The triangle at upper left and the one at lower right are similar. Ratios of corresponding sides are equal, so ...
200/a = a/2
400 = a^2
√400 = 20 = a
Then, by the Pythagorean theorem, the value of b can be found:
b = √(a^2 + 2^2) = √(400 +4) = √4·√101
b = 2√101

Answer:
Step-by-step explanation:
Given : 
We have to write which identity we will use to prove the given statement.
Consider
Take left hand side of given expression 
We know
Comparing , we get, a= 180° and b = q
Substitute , we get,
Also, we know 
and 
Substitute, we get,
Simplify , we get,
Hence, use difference identity to prove the given result.
