Answer:

Angle A = 41, Arc CE = 42, Angle C = 41, Angle D = 40, Angle ABE = 61

Step-by-step explanation:

Angle A = Arc BD/2 (Inscribed Angle)

Angle A = 82/2

Angle A = 41

Arc CE = 2 x Angle CEB (Inscribed Angle)

Arc CE = 2 x 21

Arc CE = 42

Angle C = Arc BD/2 (Inscribed Angle)

Angle C = 82/2

Angle C = 41

Angle D = Arc AC/2 (Inscribed Angle)

Angle D = 80/2

Angle D = 40

Angle ABE = Arc AE/2

Angle ABE = Arc AC + Arc CE/2

Angle ABE = 122/2

Angle ABE = 61

Find the side of a cube whose surface area is 600cm²

expeople1 [14]

Answer:

10 cm

Explanation:

Surface area of cube = 600 cm^2

Side of a cube = ?

Formula:

Total S.A of cube = 6 x (side of cube)^2

= 6 . x^2

600 cm2 = 6 . x^2

x^2 = 600 / 6

x^2 = 100

x = 10 cm

The required side of a cube = 10 cm

I need an answer please! The question says Find the value of x that would make the following expression equivalent to sixteen ti

aev [14]

Square root of 6 times 16 will give us 39.19

The square root of 48 times 32 [which gives us 1536] is also equal to 39.19

The square root of 1536 is equal to 39.19

Hence, x is equal to 32

Hope this helped! :D
