Yes, this is true. It would be different if the parenthesis were surrounding a smaller area and leaving numbers out, but it is true.

If x and x+ 10 are a pair of adjacent angle find them

ikadub [295]

Answer:

85° and 95°

Step-by-step explanation:

Given that , x and x + 10 are a pair of angles .

If they will be pair of angles on the same line , then their sum will be 180° .

=> x + x + 10° = 180°

=> 2x = 180° -10°

=> 2x = 170°

=> x = 170°/2

=> x = 85° .

<h3>Hence the two angles are 85° and 95° .</h3>

1. Solve 3x + 3 =21

sveta [45]

1.

3x + 3 = 21

3x = 21-3

3x = 18

x = 18/3

Therefore,
x = 6

So option ( B) is the correct one.

2.

$\frac{3x}{2} - 4 = 16 \\ \frac{3x}{2} = 16 + 4 \\ \\ \frac{3x}{2} = 20 \\ 3x = 20 \times 2 \\ 3x = 40 \\ x = \frac{40}{3} = 13 \frac{1}{3}$

Therefore option (B) is the correct one here too.
