Question

Find the values of x and all the three angles of a triangle,if the angle of a triangle are (2x-7)° ,(x+25)° and (3x+12)°​

Answer 1

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation.

Answer 2

Answer:

X=25. The angles are 43°,50° and 87°

Explanation:

the sum of angles in a triangle is 180°.

So adding all the angles to equal 180

2x-7+x+25+3x+12= 180

6x+30=180

6x=150

X=25

substituting X to get the angles

2x-7=43

X+25=50

3x+12=87
