Answer:
6.7 cm
Step-by-step explanation:
To make use of the Law of Sines for finding b, you need to know the missing angle B. Since the sum of the angles of a triangle is 180°, you can find angle B as ...
B = 180° -82° -55° = 43°
Now, you put the numbers you know into the formula given and solve for b.
sin(A)/a = sin(B)/b
sin(55°)/(8 cm) = sin(43°)/b
Cross multiplying gives ...
b·sin(55°) = (8 cm)·sin(43°)
and dividing by the coefficient of b gives you ...
b = (8 cm)·sin(43°)/sin(55°) ≈ 6.7 cm
Answer:
( 1, -2)
step-by-step explanation:
- original coordinates of C: (4, -2)
if reflected over y-axis: use the formula: (x,y) → (-x,y)
- new coordinates: (-4, -2)
then if translated 5 units horizontally, there will be change in x axis:
- new coordinates: (-4+5, -2) → ( 1, -2)
Answer:
25
Step-by-step explanation:
125^2=125*125=15625
125^4/3=cube root of 125^4=cube root of 244240625=625
15625/625=25
Answer:
256, -256
Step-by-step explanation:
Absolute value simply removes the negative and does nothing to positive numbers
I think those were absolute value bars. not sure.
