Step-by-step explanation:

<em>ap</em><em>p</em><em>ly </em><em>angle</em><em> </em><em>sum </em><em>property</em><em> </em><em>of </em><em>triangle</em><em> </em><em>in </em><em>the </em><em>given</em><em> </em><em>traingle </em><em>(</em><em> </em><em>instead</em><em> </em><em>of </em><em>this </em><em>u </em><em>can </em><em>write</em><em> </em><em>sum </em><em>of </em><em>all </em><em>the </em><em>interior</em><em> </em><em>angles </em><em>of </em><em>triangle</em><em> </em><em>is </em><em>1</em><em>8</em><em>0</em><em>°</em><em>)</em>

<em>so,</em>

<em>→</em><em> </em><em>8</em><em>0</em><em>°</em><em> </em><em>+</em><em> </em><em>5</em><em>0</em><em>°</em><em> </em><em>+</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em>

<em>→</em><em> </em><em>1</em><em>3</em><em>0</em><em>°</em><em> </em><em>+</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em>

<em>→</em><em> </em><em>x </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em><em>°</em><em> </em><em>-</em><em> </em><em>1</em><em>3</em><em>0</em><em>°</em>

<em>→</em><em> </em><em>x </em><em>=</em><em> </em><em>5</em><em>0</em><em>°</em>

<em>therefore</em><em>,</em><em> </em><em>value</em><em> </em><em>of </em><em>x </em><em>is </em><em>5</em><em>0</em><em>°</em><em>.</em>

Answer:

50 degrees

Step-by-step explanation:

The angles in a triangle add up to 180 degrees.

Therefore:

x + 80 + 50 = 180

x + 130 = 180

Make x stand alone by moving 130 to the other side. When 130 moves across the = it becomes negative

x = 180 - 130

x = 50

What is the volume of a sphere with a radius of 6in? Round to the nearest hundredth. Remember V = 4/3πr3 * 20 points 457.86 inch
kakasveta [241]

Given:

The radius of the sphere is 6 in.

To find:

The volume of the sphere.

Solution:

We know that, the volume of a sphere is

V=\dfrac{4}{3}\pi r^3

Where, r is the radius of the sphere.

Putting r=6, we get

V=\dfrac{4}{3}\pi (6)^3

V=\dfrac{4}{3}\pi (216)

V=288\pi

V\approx 904.78

The volume of the sphere is 904.78 inches cubed.

Therefore, the correct option is C.

Suppose the current cost of gasoline is
Elodia [21]

Answer:

The current price index number is $604.2.

Step-by-step explanation:

The index value is the ratio between the current value and the reference value, multiplied by 100.

In this problem, we have that:

Current value = $3.48

Reference value: $0.576

Index price = (3.48/0.576)*100 = $604.2.

The current price index number is $604.2.
