Question

Find the angles marked with letters a, b and c.
​

Answer 1

Step-by-step explanation:

• length of angle c :- 180-94(because they are in linear pair angles)

180-94= 86

length of angle c is 86 digree.

• length of angle a is 86 digree (because they are alternate angle)
• length of angle which is opposite of angle a =94 digree
• therefore, length of angle b=angle c +94 + angle b = 180
• angle b =86+94+ b =180
• = 180+b= 180
• b= 180-180 = 0
• length of angle b is 0

• length of angle a,b, and c are 86,0 and 86 respectively.

Answer 2

Answer:

a = 133° , b = 47° , c = 86°

Step-by-step explanation:

a straight line is 180°

so,

94°+ c = 180°

c = 86°

In Isosceles triangle property ,

two of them is equal so , b = ( near b ) d

b = d = 47°

Then ,

c + b = a

86° + 47° = 133°

a = 133°

b = 47°

c = 86°
