Answer:
14
Step-by-step explanation:
Simplify the following:
5 - 2×9 + 9^2/3
Hint: | Evaluate 9^2.
9^2 = 81:
5 - 2×9 + 81/3
Hint: | Reduce 81/3 to lowest terms. Start by finding the GCD of 81 and 3.
The gcd of 81 and 3 is 3, so 81/3 = (3×27)/(3×1) = 3/3×27 = 27:
5 - 2×9 + 27
Hint: | Multiply -2 and 9 together.
-2×9 = -18:
5 + -18 + 27
Hint: | Evaluate 5 + 27 using long addition.

Answer:
8.62
Step-by-step explanation:
a squared + b squared = c squared
15 squared + b squared = 17.3 squared
225 + b squared = 299.29
b squared = 74.29
b = 8.619
Answer:
a) 5.6
Step-by-step explanation:
sin 22° = x/15
