Answer:

<h3><u>5) Ans;</u></h3>

The two angle 7 and 8 —> 7x and 8x

Sum of two supplementary angle is 180°

7x +8x =180

15x =180

x= 180/15

x = 12°

7x =7(12)= 84°

8x = 8(12)= 96°

The angles; 84° , 96°

<h3><u>6) Ans; </u></h3>

The two angle 4 , 5 —> 4x and 5x

Sum of two complimentary angle is 90°

4x+5x =90

9x =90

x=90/9

x=10

4x—> 4(10) = 40°

5x —> 5(10) = 50°

The angles; 40° , 50°

<h3><u>7) Ans;</u></h3>

q= 135 ( Vertically Opposite angles)

q+p = 180

135+p=180

p=180-135

p = 45°

_______o_____o_____

a= 70° ( Alternate angles)

a+ b = 180

70 + b = 180

b =180 - 70

b = 110

So ; angle a=70° , b = 110°

I hope I helped you^_^

Two less than three times a number is equal to 19. What is the number?
EastWind [94]

The best way to approach a word problem like this

is to break it down into pieces, so we can understand it fully.

In this problem, we have a number, which we don't know.

We can use any variable to represent it.

So let's use the variable <em>n</em> to represent it.

"Two less than three times a number" means 3n - 2.

A common mistake is for students to put 2 - 3n.

However, the word "less than" switches the order around.

So we have 3n - 2 = 19.

Solving from here, we add 2 to both sides to get 3n = 21.

Now divide both sides of the equation by 3 and we have n = 7.

So the number is 7.
