Answer:
sin(B) = 2/3
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side.
sin(B)/b = sin(A)/a
sin(B)/8 = sin(30°)/6 . . . . fill in the given values
sin(B) = 8(1/2)/6 . . . . . . . .multiply by 8
sin(B) = 2/3
Answer:
x = 4
Step-by-step explanation:
90 + 70 + 5x = 180
160 + 5x = 180
180 - 160 = 20
20 / 5 = 4
Answer:
221 mm
Step-by-step explanation:
The dimension 74 mm is presumed to mean that the actual length could be anywhere in the interval [73.5, 74.5). So, the minimum perimeter is ...
3 × 73.5 = 220.5 ≈ 221 . . . millimeters
_____
The perimeter of an equilateral triangle is 3 times the side length, since all three sides of the triangle are the same length.
