Question

great math question for class 6 and 7 ​

Answer 1

Answer:

X = 70 degree, Y = 30 degree and Z = 110 degree

Step-by-step explanation:

We know that,

Sumof two angles is equal to 3rd angle

According to question

(30+80)degree - 180 degree = x degree

70 degree = x degree

Now,

30 degree = y degree ( Angle opposite to equal sides are equal )

Again,

( 35+30 ) degree - 180 degree = Z degree

115 degree = Z degree

HOPE IT HELPS

Answer 2

Answer:

value of y

1. y+30=180(linear pair angles)
2. y=180-70
3. y=110 degrees

value of x

1. 30+80+x=180(angle sum property)
2. 110+x=180
3. x=180-110
4. x=70 degree

value of z

1. 35+y+angle below z=180(angle sum property)
2. Let angle below z be w...
3. 35+110+w=180
4. 145+w=180
5. w=180-145
6. w=35 degree
7. w+z=180(linear pair angles)
8. 35+z=180
9. z=180-35
10. z=145 degree.

My pleasure to answer!!!
