Find the measure of angle A

Mathematics
1 answer:
Westkost [7]3 years ago
6 0

Answer:

35 degrees

Step-by-step explanation:

Sum of angles inside a triangle is 180 degrees.

Right angle is 90 degrees.

180 = 90 + (x + 46) + (x + 66) = 2x + 202

x = -11

A = x + 46 = -11 + 46 = 35

Make x the subject of the formula y=(5t+5x)
Elan Coil [88]

Answer:

(y-5t)/5=x

Step-by-step explanation:

y=5t+5x

factorize

y=5(t+x)

divide both sides by 5

y/5=5(t+x)/5

y/5=t+x

make x to stand alone

y/5-t=x

take lcm of 5 and 1

y/5-5t/5

y-5t/5=x

If the volume of a sphere inscribed in a cubic box is 36pi, find the surface area of the box
Kruka [31]

Answer:

Surface area of the cube = 216 square units

Step-by-step explanation:

Let the length of a side of a cube = x unit

Diameter of the sphere inscribed in this cube = length of a side of the cube

Volume of the sphere = \frac{4}{3}\pi r^{3}

Where r = radius of the sphere = \frac{x}{2} units

36π = \frac{4}{3}\pi (\frac{x}{2})^{3}

36π = \frac{4x^{3}\pi }{24}

36×24 = 4x³

x = \sqrt[3]{\frac{36\times 24}{4} }

x = 6 units

Length of a side of the cube = 6 units

Surface area of the cube = 6×(Side)²

                                          = 6×(6)²

                                          = 216

                                          = 216 square units
