Question

find the value of y in the given triangle​

Answer 1

Answer:

55

Step-by-step explanation:

70+y+y=180 angle sum property

70+2y=180

y=110/2

y=55

Answer 2

Given,

The value of one angle of the given triangle = 70°

Other two angles are equal and their value is "y".

To find,

The numerical value of "y".

Solution,

We have to keep in mind, that the sum of three angles of a triangle is always 180°. This data will help us to solve this mathematical problem.

Sum of the three angles with the given values = 70+y+y = (70+2y)°

Now, according to the previously mentioned data,

70+2y = 180

2y = 180-70

2y = 110

y = 55

Hence,the value of y is 55°.
