two angles form a linear pair. If one angle is 7/2 larger than the other, what is the measurement of each angle.​
masha68 [24]

The angles are 40 degrees and 140 degrees.

• In plane geometry, a figure which is created by two rays or two lines or line segments that share a common end point is known as angle.

• The two rays which are share a common point are called as sides of the angle an the common end point is called as the vertex.

• Some types of angles are acute angle, right angle, obtuse angle, straight angle and many more.

Let one angle be x

Other angle = 7/2 x

Since it is a linear pair, it’s sum will be 180 degrees.

So, x + 7/2 x = 180

9/2 x = 180

9 x = 360

X = 40

7/ 2 x = 7/2 × 40 = 140

Therefore, the angles are 40 degrees and 140 degrees.

This will give you 35 just please help I need to do this very fast. So if you can help please do.
EleoNora [17]

Answer:

52° and 38°

Step-by-step explanation:

The two angles form a singular right angle.

(x+33)+(2x)=90\\\\x+33+2x=90\\\\3x + 33 = 90\\\\3x+33-33=90-33\\\\3x=57\\\\\boxed{x=19}

The value of 'x' is 19.

m$\angle$1 = x + 33\\\\m$\angle$1 = 19 + 33\\\\m$\angle$1 = \boxed{52}

The measure of angle 1 is 52 degrees.

m\angle2=2x\\\\m\angle2=2(19)\\\\m\angle2=\boxed{38}

The measure of angle 2 is 38 degrees.

Hope this helps.

Answer:

<em><u>135</u></em> cubes would fill the prism

Step-by-step explanation:

volume of one small cube = (1/3)^3

= 0.037 cubic units

Number of cubes that would fill the prism =

5 cubic units / 0.037 cubic units

= 135 cubes

Tammy learns in science class that water freezes when its temperature is
Oksanka [162]

The required number line that shows all of the possible

temperatures is option A.

<h3>Inequalities and number line</h3>

From the given question, we have that water freezes when its temperature is no more than 32 °F

The statement no more than 32 °F shows that the temperature cannot be greater than 32 but less than or equal to 32. This is written mathematically as;

t ≤ 32.

We are to select the number line that shows all of the possible temperatures. The required number line that shows all of the possible

temperatures is option A.
