PLEASE HELP ME!!! Find m (angle) LMN

Answers

Answer:

108°

Step-by-step explanation:

hii!

lmn would be equal to 85 plus 23.

hope this helped you :)

m[tex]\angle{LMN[/tex] is 108°.

What is an angle ?

To form an angle we need at least two rays with one common endpoint this is also known as vertex of the angle.

There are many types of angles.For example - Acute angle, Obtuse angle, Right angle, complementary angle, Supplementary angle.

The most common unit for measuring an angle is in degrees and in radians,Where 1 rad = 180°.

According to the given question.

[tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex] are given they are 85° and 23° respectively.

From the given diagram we can observe that [tex]\angle{LMN[/tex] is sum of the angles [tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex].

∴ [tex]\angle{LMP[/tex] + [tex]\angle{PMN[/tex] = [tex]\angle{LMN[/tex]

     85° + 23° = 108°.

So, [tex]\angle{LMN[/tex] = 108°.

solve and graph: 7x-6>22
(pls explain your answer, im confused on this)​

Answers

Answer:

x>4

Step-by-step explanation:

Solving an inequality is very similar to solving an equation:

Given: 7x-6>22

Add 6 to both sides: 7x>28

Divide both side by 7: x>4

x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.

How many onto functions are there from a set with three elements to a set with eight elements?

Answers

Answer:

0 onto functions

Step-by-step explanation:

Let the sets be [tex]A\ and\ B[/tex] such that:

[tex]n(A) = 3[/tex]

[tex]n(B) = 8[/tex]

Required

The number of onto functions

The condition for onto functions is:

For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A

Since n(B) > n(A) i.e. 8 > 3

Then, there can't be onto functions from A to B
