Mathematics
1 answer:
svp [43]2 years ago
7 0

Step-by-step explanation:

1. Given angles are,

40°, 3x+8° , 10x+42°

Therefore, by the problem,

=> 40° + 3x+8° + 10x+42° = 180° [Angle sum property of triangle]

=> 3x + 10x = 180° - (40°+42°+8°)

=> 13x = 180° - 90°

=> 13x = 90°

=  > x =  \frac{90}{13}

<u>Hence required value of x is (90/13)°</u>

2. Given,

12x - 18° = 5x +19° [Alternate angles]

=> 12x - 5x = 19 + 18

=> 7x = 37

=  > x =  \frac{37}{7}

<u>Hence required value of x is (37/7)°</u>

3. Given,

Exterior angle 132°

So it's paired interior angle will be = 180° - 132° (linear pair) = 48°

Hence the angles we get are = 42° , 87° , 20x - 10°

Therefore, by the problem,

48° + 87° + 20x - 10° = 180° [Angle sum property of triangle]

=> 20x = 180 - 48 - 87 + 10

=> 20x = 55

=  > x =  \frac{55}{20}

=> x = 2.75

<u>Hence required value of x is </u><u>2.75</u>

(04.02 MC)<br> Solve the system of equations.<br> 5x + y = 9<br> 3x + 2y = 4
goblinko [34]

Answer:

(2,-1)

Step-by-step explanation:

Multiply first equation by 2:

10x + 2y = 18

Subtract the second equation from this so that the 2y terms cancel:

10x - 3x = 18 - 4

7x = 14

x = 2

Plug into first equation to find y:

5(2) + y = 9

10 + y = 9

y = -1

The answer is (2,-1)
