Answer: x = 15
Step-by-step explanation:
First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.
90 = 2x + 4x
90 = 6x
= 
15 = x
Therefore, the x is 15.
The perimeter is 28 and the area is 24
Answer:
90
Step-by-step explanation:
The mode of the set is the number that occurs the most. In this case, 90 occurs more than any of the other terms. You can keep track using a tally chart:
80 |
82 |
90 ||
92 |
86 |
74 |
68 |
88 |
98 |
Answer:
A point and a line.
Further explanation:
Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g., .
The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.
Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.
These key terms cannot be mathematically defined using other known words.
A point represents a location and has no dimension (size). It is labeled with a capital letter and a dot.
A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.
A plane is a flat surface that contains many points and lines. A plane extends infinitely in all four directions. It is two-dimensional. Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.
By Sine Rule
a/sinA = b/sinB = c/sinC
Given a = 3, b = 4, A = 76°
<span>43sin76° = 4/sinB
</span>
==> sinB = 1.195380945
<span>
But sine function is only defined in the range [-1, 1], so there's no solution.
