Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
= =
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
= =
We require a pair of ratios which contain b and 3 known quantities, that is
=
OR
= → B
Answer:
572.5
Step-by-step explanation:
A=6ah + 3√(3) a²= 6·8·5+3√(3)·8²≈572.55376

Answer:
The question is asking which numbers are larger with respect to one another. An easy way to do this is to convert to decimals, or just memorize it. 1/2=0.5, 3/4=0.75, 2/3=0.666666. So descending order (largest to smallest) 3/4, 2/3, 1/2.
Answer:
13/90
Step-by-step explanation:
The decimal that you wrote is mixed non terminal decimal. Which means all the number don't repeat themselves.
The denominator of a non terminating decimal is always 9 even though it depends on the type of the decimal, whether it is simple or mixed
The denominator of the given decimal is 90. The denominator is 2 digit number since the given decimal is also 2 digit decimal even though it is under repeating bars.
And the numerator is 10, 13-3.
We subtract 3 since it is the one repeating itself.
Hope it helps ;) ❤❤❤
