Answer:
0.0000000692
Step-by-step explanation:
The number 
is written in scientific notation. To convert to standard notation adjust the decimal point to adjust the number according to the exponent. Since the exponent is -8 then the decimal point moves to the left 8 place values.
Answer: yes it is

Answer: 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.
