Question

how to find angles from the given anglesb​

Answer 1

Answer:

value of x is 39

Step-by-step explanation:

2x-8+3x-7=180°(interrior angle on the same side)

5x=195

i.e x=39

Answer 2

Step-by-step explanation:

4.L1=(2x-8)°

L2=(3x-7)°

L1+L2=180°

2x-8+3x-7=180

5x-15=180

5x=180+15

5x=195

x=39°

L1=2x-8=2(39)-8=70°

L2=3x-7=3(39)-7=110°

3.let A and B are two angles

A=x°, B=x+10

A+B=90°

x+x+10=90

2x=80

x=40

A=x=40°

B=x+10=40+10=50°

2. let A and B are two angles

A+B=180°

B=180-A

A=1/3(B)

A=1/3(180-A)

A=180/3-A/3

A+A/3=60

3A+A/3=60

4A=180

A=45°

1. two complementary angles are in the ratio 2:3

A=2x , B=3x

2x+3x=90

5x=90

x=18°

A=2x=2(18)=36°

B=3x=3(18)=54°
