Answer:
is the correct answer.
Step-by-step explanation:
Given:

To find:
if given term is written as following:

<u>Solution:</u>
We can see that the resulting expression does not contain anything under
(square root) so we need to rationalize the denominator to remove the square root from denominator.
The rule to rationalize is:
Any term having square root term in the denominator, multiply and divide with the expression by changing the sign of square root term of the denominator.
Applying this rule to rationalize the given expression:

Comparing the above expression with:

A = 5, B = 6 (Not divisible by square of any prime)
C = -10
D = 2 (positive)
GCD of A, C and D is 1.
So, 
The correct answer of

if x=4 is 272.
to solve the equation if x equals 4, you must substitute the x of the 4.

then solve by order of operations.
solve what is inside the parentheses first

then do the multiplication of the factors

then the final step, adding, to get the solution of 272
The answer is B x=13sin75/sin50
Answer:
See below.
Step-by-step explanation:
From the given info the 2 triangles are isosceles with AE = FR and ET = RP because the 2 sets of base angles are equal.
As the base angles are congruent m < E = m < R.
So the are 2 triangles are congruent by SAS, ASA and AAS.
