Answer:
120 degrees
Step-by-step explanation:
Attached is a screenshot.
y = 180 - 50 - 70 = 60.
x + y = 180, so x = 120
Remember to try to use parallel lines when you can
The second uses the same method, just the opposite side.
Which graph represents the function? g(x)={x if x<2−3 if x≥2
2 answers:
Answer:
We have to graph the function g(x) which is given as:
g(x)= x when x<2
and -3 when x ≥2.
Clearly after looking at the function we see that the function is not continuous since we find the continuity at x=2 as follows.
Left hand limitat 2:
g(2-h)=lim h→0 2-h
=2-0=2
Also right hand limit at x=2 is:
g(2+h)=lim h→0 (2+h)
= 2+0=2
Also g(2)= -3.
As:
Left hand limit= Right hand limit but is not equal to function's value at that point.
Hence, the function is discontinuous at x=2.
so for x<2 we will get a graph of a line y=x.
and for x≥2 we will get a straight line y=-3 parallel to the domain.

To answer this question, we need to recall that: "the diagonals of a rectangle bisect each other"
Thus, if we assign the point of intersection of the two diagonals in the rectangle as point O, we can say that the triangle OQR is an "isosceles triangle". Note that this is because the lengths OR and OQ are equal since we know that: "the diagonals of a rectangle bisect each other". See the below diagram for clarity.
Now, we have to recall that:
- the base angles of any isosceles triangle are equal. This is a fact, and this means that the angles
- also the sum of all the angles in any triangle is 180 degrees
Now, considering the isosceles triangle OQR, we have that:
Now, since the figure already shows that angle Now, since we have established that the base angles
we can now solve the above equation for m<2 as follows:
Therefore, the correct answer is: option D
<h3><u>Question:</u></h3>
The perimeter of a rectangle is 34 units. Its width W is 6.5 units.
Write an equation to represent the perimeter in terms of the length L, and find the value of L
<h3><u>Answer:</u></h3>The length of rectangle is 10.5 units
<h3><u>Solution:</u></h3>Given that,
Perimeter of rectangle = 34 units
Width of rectangle = 6.5 units
Let "L" be the length of rectangle
<em><u>The perimeter of rectangle is given by formula:</u></em>
Perimeter = 2(length + width)
<em><u>Substituting the values we get,</u></em>
Thus the equation is found
<em><u>Solve for "L"</u></em>
Thus length of rectangle is 10.5 units
