Question

find 'x' in the following figures ??
exercise 2.2 (ii) question​

Answer 1

Answer:

Step-by-step explanation:

= 45+68+(3x+16)=180

= 113+(3x+16)=180

= 3x+16=180-113

= 3x+16=67

= 3x=67-16

= 3x=51

= x=51/3

= x=17

Value of ∠Q is (17*3)+16

= 57+16

=73°

Answer 2

Answer:

17

Step-by-step explanation:

The angle-sum property states that the sum of all three angles of a triangle is equal to 180.

We know the value of 2 angles = 45 + 68

                                                    = 113

So, the value of the 3rd angle = 180 - 113

                                                  = 67

So, 3x + 16 = 67

   = 3x = 67- 16 = 51

  = x = 51/3

   = x = 17

Therefore, the value of x is 17.
