A triangle solver tells you
C = 85° b ≈ 8.4 c ≈ 10.4From the sum of angles of a triangle,
C = 180° -42° -53° = 85°
From the law of sines
b = sin(53°)/sin(42°)*7 ≈ 8.355
c = sin(85°)/sin(42°)*7 ≈ 10.422
Answer:
21 divided by 2 and 2/3 = 11.1666667
Step-by-step explanation:
Answer:
C) 471
Step-by-step explanation:
Surface area for a cylinder formula:
SA = 2πrh + 2πr²
Given:
r = 5
h = 10
Work:
SA = 2πrh + 2πr²
SA = 2(3.14)(5)(10) + 2(3.14)(5²)
SA = 314 + 2(3.14)(25)
SA = 314 + 157
SA = 471
TY for the 10 points answer is g 1 f 4 h 10
