Answer 1

Answer:

2. angle x+y = 180 ° linear pair

Let x and y be z , 5z and 7z respectively

Now ,

5z + 7z = 180°

12z = 180°

z = 180°/12

z = 15°

So ,

x = 5z = 5 × 15 = 75°

y = 7z = 7 × 15 = 105°

3. x + 40° = 90°

x = 90° - 40°

x= 50°

4. let the angles be x

3x + x = 180°

4x = 180°

x = 180°/4

x = 45°

3x = 135°

So , one angle is 45° and another is 135°

5. 3x + 10 = 90°

3x = 90° - 10

3x = 80°

x = 80° /3

x = 26

So , 2x = 56°

3x+10 = 90°

And the whole angle is

90° + 56° = 146°

Answer 2

Answer:1= 76

             2= x=105,y=75

             3= x=50

             4= x=34

Step-by-step explanation:

1:- complementary angle= 90 d

let the second angle be X

14+x=90

x=90-14

x=76

2:- x:y=5:7=180

multiply 7 by x and 5 by y

7x+5y=180

12x=180

x= 180/12

x= 15

multiply 7 and 5 by 15

therefore x=105, y=75

3:- Let The Second Angle Be x

Since the angle is a right angle

40+X=90

X=90-40

x=50

4:- 180-x=3(90-x)

180-x=270-3x

-x =3x=270-180

2x=90

X=90/2

X=45

5:- 3x+10+2x=180

   5x+10= 180

   5x= 180-10

   5x=170

   x  = 170/5

   x= 34
