Question

the angels of a triangle are (2n-7)° , (x+25)° . and (3x12)° .find the measure of angles​

Answer 1

Appropriate Question:-

The angles of triangle are (2x-7) , (x + 25) and (3x +12) Find measure of angles

Lets understand:-

The queation says that there are 3 angles which they have measured in Triangle We have to find that 3 angles

Concept to know :-

Sum of three angles in a triangle is 180°

_____________________________

So, the three angles sum should be 180°

2x - 7 + x + 25 + 3x + 12 = 180°

2x + x + 3x - 7 + 25 + 12 = 180°

6x + 30 = 180°

6x = 180°-30°

6x = 150°

x = 150°/6

x = 25°

Finding angles :-

2x - 7

= 2(25)-7

= 50-7

= 43

x + 25

= 25+25

=50

3x + 12

= 3(25) +12

= 75+12

=87

So, three angles in triangle are 43°,50°,87°

____________________

Verification:-

We got three angles their sum should be 180°

43° + 50°+87° = 180°

180° = 180°

Hence verified

LHS = RHS
