What is the value of x?<br> A. 25°<br> B. 50°<br> C. 55°<br> D. 75°<br> E. 80°
Troyanec [42]

Answer:

<h2><em><u>Option</u></em><em><u> </u></em><em><u>B</u></em></h2><h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>50</u></em><em><u>°</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<em><u>By</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>condition</u></em><em><u>, </u></em>

25° + 105° + x = 180° <em>[</em><em>Angle</em><em> </em><em>sum</em><em> </em><em>property</em><em> </em><em>of</em><em> </em><em>triangle</em><em>]</em>

=> 130 + x = 180

=> x = 180 - 130

=> <em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>50</u></em><em><u>°</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

This table gives a few (x, y) pairs of a line in the coordinate plane.
katrin2010 [14]

Answer:

The x-intercept is : (22, 0)

Step-by-step explanation:

From the table values, we determine that it is a straight line as there is a constant change in x and y values.

i.e.

Any previous value of y can be obtained by subtracting 15 from the successor y value.

i.e.

60 - 15 = 45

45 - 15 = 30

so if continue, we can also determine some of the other values of y such as

30 - 15 = 15

15 - 15 = 0

Also, there is a constant change in x values. so, any previous value of x is obtained by subtracting 13 from the successor x value.

i.e.

74-13 = 61

61-13 = 48

48-13=35

35-13=22

So, from the above analysis, we determine that when the value of y = 0, the value of x = 22.

We also know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.

so, at y = 0, the value of x = 22.

Therefore, the x-intercept is : (22, 0)

What is the area and perimeter of the triangle?
Fofino [41]

Answer:

perimeter= 17/3

area= 12

Step-by-step explanation:

for perimeter:

basically you need to add all sides

so to make it easier yo can put the equation in this way

4/3 + 5/3 + 8/3 = (and that gives you) 17/3

given they have common denominator you just add the numbers

for area:

the equation of the area of a triangle is:

1/2 x base x height

you just need to replace to end up with

1/2 x 8/3 x 6 = 12
