A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11

Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°

Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°

60% were parents.

<u>To find:</u>

Number of parents attended.

Solution:

1. 60% of 120

It can also be written as:

\frac{60}{100}\times \frac{120}{1}

Simplify

  • Cancel zeros

\frac{60}{100}\\\\=\frac{6}{10}

  • Divide by common factor (2)

\frac{6\div2}{10\div2}=\frac{3}{5}

2. \bold{\frac{3}{5}\times \frac{120}{1}}

Multiply

\frac{3\times120}{5\times1} = \frac{360}{5}

Divide

\frac{360}{5}= 360\div5=72

Therefore, 72 parents attended the game.
