Answer:

x = 75°

Explanation:

From question diagram, we observe that

Two angles of a triangle is given.we have to find the third angle.

Since, we know that the sum of angles is 180°.

the value of first angle = 35°

the value of second angle = 70°

the value of third angle = x = ?

hence, we can write

35° + 70° + x = 180°

105°+x = 180°

Adding -105° to both both sides of above equation,we get

-105° + 105° + x = -105° + 180°

x = 75° which is the answer.

Answer:

The value of x = 70° ,

Right option is : A . 70°

Explanation:

We have given one triangle,

One angle of triangle = 70°

Another angle of triangle = 35°

we need to find the third angle (let the third angle be x).

Since sum of angle of triangle is 180°

So, Sum of all three angles = 180°

i.e 70° + 35° + x = 180°

or 105° + x = 180°

or x = 180° - 105°

or x = 75°

Hence the value of x = 70°
