frutty [35]3 years ago

Answer:

30

Firstly, identify all the pairs of vertically opposite angles. Vertically opposite angles are equal.

In this case,

AOC & DOB are vertically opposite angles so both of them are 2x°

EOD & COF are vertically opposite angles so they are both 3x°.

FOB & EOA are vertically opposite angles so they are both x°.

Adding the values of all 6 angles, we get:

3x + 3x + 2x + 2x + x + x = 12x

We also know that

12x = 360°

x = 30°

The function is defined by the following rule.<br> f(x)=2x+4<br> Complete the function table.
11111nata11111 [884]

Answer:

-3   -2

-2   0

-1   6

3  10

4  12

Step-by-step explanation:

f(x)=2x+4

Let x = -3  f(-3) = 2*-3 +4 = -6+4 = -2

Let x = -2  f(-2) = 2*-2 +4 = -4+4 = 0

Let x = -1  f(1) = 2*1 +4 = 1+4 = 6

Let x = 3  f(3) = 2*3 +4 = 6+4 = 10

Let x = 4  f(4) = 2*4 +4 = 8+4 = 12

∠LMN and ∠PQR are complementary angles. Find m∠LMN if m∠LMN = (4x-2) and m∠PQR= (9X+1)
kow [346]

Answer:

<h2>m∠LMN = 26°</h2>

Step-by-step explanation:

Since ∠LMN and ∠PQR are complementary it means that the sum of their angles is 90°

To find m∠LMN , add both m∠LMN and m∠PQR and equate it to 90 to find x then substitute the value of x into the expression for m∠LMN

That's

m∠LMN + m∠PQR = 90

4x - 2 + 9x + 1 = 90

13x - 1 = 90

13x = 90 + 1

13x = 91

Divide both sides by 13

x = 7

From the question

m∠LMN = (4x-2)

m∠LMN = 4(7) - 2 = 28 - 2

We have the final answer as

<h3>m∠LMN = 26°</h3>

Hope this helps you
