Answer 1

Explanation:

3.   Three times a number m is = 3m

     Also given that,

     Three times of the number m is 20.

     So, by the problem the equation formed is

      3m = 20  (Ans)

4. We have to find the supplement of 145°, so

    we know that two angles are called supplementary when their measures add up to 180°.

Let the another supplementary angle be = x

∴ By the condition,

=> 145° + x = 180°

=> x= 180° - 145°

=> x= 35°

Hence, 35° is another supplementary angle (Ans)

     

Answer 2

Explanation:

4. Two angles are Supplementary if the two angles add up to 180°

supplementary of

145°

= 180° - 145=35° answer.

I am sure for answer 4.

3.Let the number be x.

Since 3 times of the number i.e. 3*x is add from seven times the number i.e. 20*x

This implies 20*x-3*x=

20x -3x=17.

but I am not sure for answer 3. sorry
