Question

find the values of the unknown ‘x’ and ‘y’in the following diagrams.​

Answer 1

Answer:

(iii) sum of angles of a triangle is 180

NMA=50°

MAN=60°

60+50= 110°

110-180=70°

SO Y IS 70°

X=180°-70°(LINEAR PAIR)

X = 10°

Answer 2

Step-by-step explanation:

Given,

< NMA = 50 °

< MAN = 60 °

We know that Sum of interior angles of a triangle is 180 °

According to the question,

y + 60° + 50° = 180°

y + 110° = 180°

Transpose 110 ° to the right

y = 180° - 110°

y = 70°

Now x = 180 ° - 70° ( Linear Pair)

X = 110°
