Answer:
55.56%
Step-by-step explanation:
= (20 / 36) × 100
= 0.56 × 100
= 55.56%
It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
Answer:
17.7
Step-by-step explanation:
angle B = 180 - 81 - 65 = 34 degrees
as the sum of all angles in any triangle is always 180 degrees.
a/sin(A) = b/sin(B) = c/sin(C)
the sides are always on the opposite side of the angle.
so,
10/sin(34) = AB/sin(81)
AB = 10×sin(81) / sin(34) = 17.7
