Angle x and angle y are complementary. Angle x is supplementary to a 128 degree angle. What are the measures of angle x and angl

alexdok [17]

The measurement of angle x is 52° and y is 38°

Step-by-step explanation:

Let us define supplementary and complementary angles first.

Supplementary angles is pair of angles whose sum is 180°

While complementary angles sum up to 90°

Given

That x and y are complementary and x is supplementary to 128.

This means that sum of x and 128 is 180°

So,

$x+128 = 180\\x = 180-128\\x = 52$

So,

x = 52°

It is also given that x and y are complementary which means that

$x+y = 90\\52+y = 90\\y = 90-52\\y = 38$

Hence,

The measurement of angle x is 52° and y is 38°

The volume of a cube is 125m3 if I L of a paint covers 6m2, how many liters of paint are needed to paint the outside of the cube

Effectus [21]

Answer:

36 liters

Step-by-step explanation:

step 1

Find the length side of the cube

we know that

The volume of the cube is given by

$V=b^3$

we have

$V=125\ m^3$

substitute

$125=b^3$

solve for b

$b=5\ m$

step 2

Find the surface area of the cube

The surface area of a cube is equal to

$SA=6b^2$

substitute the value of b

$SA=6(6)^2=216\ m^2$

step 3

Find out how many liters of paint are needed to paint the outside of the cube

we know that

1 L of a paint covers 6m2

so using proportion

$\frac{1}{6}\ \frac{L}{m^2} =\frac{x}{216}\ \frac{L}{m^2} \\\\x=216/6\\\\x=36\ L$
