Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

x = (65)

  • 20 + 55 + 40 = 115
  • 180 - 115 = 65
  • Therefore, x = 65

Answer:

x = 65.

Step-by-step explanation:

= 20 + 55 + 40

The diagram shows several planes, lines, and points.
Aleksandr-060686 [28]

Answer:

The true statement is <u>Line h has points on planes R, P, and T</u>

Step-by-step explanation:

The rest of the question is the attached figure

According to the graph, we will check which option is true.

a. Line h intersects line f at two points, A and B   (<u>Wrong</u>)

<u>Because</u>: h intersects line f at B only.

b. Line h is the intersection of planes R and T      (<u>Wrong</u>)

<u>Because</u>: g is the intersection of planes R and T

c. Line h intersects plane P at point C                   (<u>Wrong</u>)

<u>Because</u>: h intersects plane P at point B

d. Line h has points on planes R, P, and T             (<u>True</u>)        

<u>Because </u>h has the point B on the plane P, h has the point A on the plane T

and the points of h on the plane R

When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither nu
o-na [289]
The answer would be A. When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system has infinite solutions. It would be hard finding this answer when we use the Cramer's Rule so instead we use the Gauss Elimination. Considering the equations:

x + y = 3 and <span>2x + 2y = 6
Determinant of the equations are </span>
<span>| 1 1 | </span>
<span>| 2 2 | = 0
</span>
the numerator determinants would be
<span>| 3 1 | . .| 1 3 | </span>
<span>| 6 2 | = | 2 6 | = 0.
Executing Gauss Elimination, any two numbers, whose sum is 3, would satisfy the given system. F</span>or instance (3, 0), <span>(2, 1) and (4, -1). Therefore, it would have infinitely many solutions. </span>
