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><u>Hence </u><u>the </u><u>two </u><u>angles</u><u> </u><u>are </u><u>8</u><u>5</u><u>°</u><u> </u><u>and </u><u>9</u><u>5</u><u>°</u><u> </u><u>.</u></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.
