Answer:
Perimeter = 54.6 cm
Area = 173 cm²
Step-by-step explanation:
sin 30 = x/20
x = 10
cos 30 = y /20
y = 17.3
perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm
area = 10 * 17.3 = 173 cm²
14 hours.......200 divided by 15 is 13.3333333 so your answer is 14
hope i could help sorry if i get it wrong
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
If Emily has 6 cubes of 3 x 3 x 3, or 27 cubic cms. each, and these completely fill the prism, then the prism must be:
27 x 6, or 162 cms.^3 total volume. ☺☺☺☺
Answer:
2s + 30 = 2s
Step-by-step explanation:
