Answer 1

Answer:

x = 56°

Step-by-step explanation:

Base angles of an isosceles triangle are equal.

This:

The angle of the triangle to our right, which is the third unequal angle = 180 - 2(31)

= 180 - 62

= 118°

The base angle of the triangle to our left = 180 - 118 (angles on a straight line)

= 62°

x = 180 - 2(62)

x = 180 - 124

x = 56°

Answer:

x = 115° , y = 140° , z = 40°

Step-by-step explanation:

40° , x and 25° lie on a straight line and sum to 180° , that is

x + 40° + 25° = 180°

x + 65° = 180° ( subtract 65° from both sides )

x = 115°

z and 40° are vertically opposite angles and are congruent , then

z = 40°

y and z lie on a straight line and sum to 180° , that is

y + 40° = 180° ( subtract 40° from both sides )

y = 140°

Solve the literal equation for y, 2x-2y=5

Answers

We can see here that the equation solved for y is: y = (2x - 5) / 2.

How we arrived at the solution?

To solve the given literal equation for y, follow these steps:

Given equation: 2x - 2y = 5

Step 1: Subtract 2x from both sides of the equation to isolate the term with y on the left side.

2x - 2y - 2x = 5 - 2x

-2y = -2x + 5

Step 2: Divide both sides by -2 to solve for y.

(-2y) / -2 = (-2x + 5) / -2

y = (2x - 5) / 2

So, the equation solved for y is: y = (2x - 5) / 2.

What is the radius of a sphere with a volume of 572 cm", to the nearest tenth of a
centimeter?

Answers

Answer:

The radius of a sphere with a volume of 572 cm^3 is 5.15 cm

Step-by-step explanation:

We need to find the radius of a sphere whose volume is: 572 cm^3

The formula used will be: $Volume=(4)/(3) \pi r^3$

Putting value of Volume =572 and π=3.14 we can find radius (r) of a sphere.

$Volume=(4)/(3) \pi r^3\n572= (4)/(3)*3.14*r^3\n572=4.187*r^3\nr^3=(572)/(4.187)\nr^3=136.613\nTaking \ cube \ root \ on \ both \ sides:\n\sqrt[3]{r} =\sqrt[3]{136.613} \nr=5.15 \ cm$

So, the radius of a sphere with a volume of 572 cm^3 is 5.15 cm
