Question

Find 'x' of the following.

please tell to me fast​

Answer 1

Step-by-step explanation:

Sum of all angles in a triangle = 180°

I) 2x° + (x + 7)° + 35° = 180°

2x° + x° + 7° + 35° = 180°

3x° + 42° = 180°

3x° = 180° - 42°

3x° = 138°

x = 138/3

x = 46°

Answer 2

Answer:

Step-by-step explanation:

1) 3x+7+35=180(angle sum property)

3x+42=180

3x=180-42

3x=138

x=138/3

x=46

2)first we should find the opposite angle to 137° angle so,

137+angle opposite to it =180°(linear pair)

angle opposite to it =180-137

angle opposite to it =43

so we found angle opposite to it now,

x+56+43=180(angle sum property)

x+99=180

x=180-99

x=81
