Answer:
is 60
Step-by-step explanation:
Step-by-step explanation:
first of all, as the sum of all angles in a triangle is always 180°, the missing angle B is
B = 180 - 89 - 30 = 61°
the law of sine is
a/sin(A) = b/sin(B) = c/sin(C)
where the sides are always opposite of the associated angles.
14/sin(61) = AB/sin(30) = BC/sin(89)
BC = 14×sin(89)/sin(61) = 16.00451901...
so, 16 is the correct answer.
Answer:
2/3
Step-by-step explanation:
Simplifying the Complex Fraction
Convert Mixed Numbers to Fractions
56114=5654
Method 1 : LCD Multiplication
The LCD for 6 and 4 is 12
Multiply top and bottom by the LCD
12×5612×54=1015
convert to mixed numbers and
reduce fractions where possible
=1015=23
Method 2 : Fraction Division
Divide the top fraction by the bottom
(multiply top by reciprocal of bottom)
56÷54
=56×45
=2030
convert to mixed numbers and
reduce fractions where possible
=2030=23
Answer:
149
Step-by-step explanation:
5 to the second power is 25, because you do 5x5. Then you multiply 25 by x, which is 6, and get 150. Then you add 6 to 150, which is 156, and subtract seven. Also the answer is 149.
Answer:
r = 5. 5^3 = 5x5x5 = 125. hope this helps
