Question

1. if x=70 find y and z
2. if 3x=2y,find x.
3. if z=2(x+15),find y​

Answer 1

Answer:

1.z=110,y=110

2.x=30

3.y=130

Step-by-step explanation:

1. if x= 70

then angle ACD will also be equal to 70

so angle z=180-70

=110

angle z=angle y

angle y = 110

2. if 3x=2y then

angle z will also be 2y

and Angle ACD will be 3x

so

3x+2y=180

3x+3x=180 (3x=2y)

6x=180

x=30

3. angle z=angle y

y=2(x+15)

=2x+30

first find x

angle x + angle y = 180

x+2x+30=180

3x+30=180

3x=150

x=50

y=180-50

=30
