A and B are equal to 27^-1
9⁹ ÷ 9⁶.
The expression 9³ is equivalent to 9⁹ ÷ 9⁶.
Using the law of exponents aⁿ÷aˣ = aⁿ⁻ˣ
9⁹÷9⁶= 9⁹⁻⁶ = 9³
Answer:
BC = 24
Step-by-step explanation:
Since angle B is equal to angle C
AC = AB
3x-15 = x+33
Subtract x from each side
3x-15 -x=x+33-x
2x-15 = 33
Add 15 to each side
2x-15+15 = 33+15
2x = 48
Divide by 2
2x/2 = 48/2
x = 24
We want BC = x
BC = 24
Answer:
the answer for e is -2 and f is 2
Step-by-step explanation:
because if ever look at it E and F are straight from each other so one would be a negetive nunber and the other would be a positive number.
Answer:
Step-by-step explanation:
Side c = AB can be found using the Pythagorean theorem:
c² = a² + b² = 8² +5² = 89
c = √89 ≈ 9.43
__
Angle B is the complement of angle A, so is ...
B = 90° -A = 90° -58° = 32°
c is approximately 9.43; the measure of angle B is 32°.
