Opposite angle of a quadrilateral add up to 180 degrees.

This means Angle A plus Angle C equal 180.

We can solve for X using that, then solve for Angle B.

2x-7 + x +4 = 180

Simplify:

3x -3 = 180

Add 3 to each side:

3x = 183

Divide both sides by 3:

x = 183 /3

x = 61

Now we know x, replace x with 61 in the equation for Angle B:

Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.

Which statement is true of every plane in three-dimensional space?
leonid [27]

Answer:

option A is correct.(Every plane must have three intercepts.)

Step-by-step explanation:

" Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension "

The intercept form of the equation of plane in 3-D is given by:

\dfrac{x}{l}+\dfrac{y}{m}+\dfrac{z}{n}=1

Where l,m,n are intercepts of x,y,z axes and a plane respectively.

Hence, we require all the three intercepts of a every plane.

Hence, option A is correct.

1. A professional basketball used for league play has a diameter of 25 cm. Which of the following is closest to the volume of th
yKpoI14uk [10]

Answer:

V = 8,181.23 cm^{3}

Step-by-step explanation:

Unfortunately, we are not given any answer choices to choose from but using the information provided we can find the actual volume of the basketball. A basketball is made in the shape of a sphere and the formula for the volume of a sphere is the following...

V = \frac{4}{3} * \pi  * r^{3}

radius of a circle/sphere is half of it's diameter. Since we are provided the diameter size we simply divide it by 2 which would give us 12.5cm. Now we simply plug this value into the formula and solve for V.

V = \frac{4}{3} * \pi  * 12.5^{3}

V = \frac{4}{3}  * \pi  * 1953.125

V = 8,181.23 cm^{3}
