Question

23. Find the value of y in the diagram below."
35
65°​

Answer 1

The sum of all angles is 180° cuz it's a straight angle.

So, 35°+65°+y = 180°

100°+y=180°

y= 180°-100°=80°

Answer 2

Answer:

Y= 80°

Step by step explanations.

Sum of all angles on a line measure 180°.

=>angle a+ angle b+ angle c = 180°.------(1)

(NOTE-You will use the symbol of angle instead of writing angle , as I can't write this symbol in phone)

Now, we have angle a=35°

angle b= 65°

angle c= Y

Put the value of a and b in (1).

We get..,,,

35°+65°+angle c= 180°

=>. 100°+ angle c= 180°

=>. angle c= 180°- 100°

=>. angle c= 80°

•°• Y = 80°

Work hard to write it so thanks my ❤️❤️❤️ answers.
