When I triple my number, add five and add my number I get twenty five what is my number?

5

Step-by-step explanation:

Let x be the number.

Triple the number: 3x

Add 5: 3x + 5

Add the number: 3x + 5 + x = 4x + 5

4x + 5 = 25

4x = 20

x = 5

Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.
