Question

Mhanifa u helped me with this question.... U said it was 25 and its not so why is it wrong

Answer 1

Step-by-step explanation:

As we can see it is an isosceles triangle so

2x + 2° + 2x + 2° + 3x + 1°= 180° { being sum of angles of triangle }

7x + 5 = 180°

7x = 180° - 5°

7x = 175

x = 25°

25 is the correct answer..

Answer 2

Hey I don't know who Mhanifa is but 25 is correct, and I will put the entire explanation to how to get the answer here.

First of all the 2 lines on the left and right side of the triangles are means that those 2 lines are equal and thus forming a isosceles triangle.

This means that the bottom right angle is also 2x+2 degrees.

Now because all 3 angles in a triangle adds to 180 degrees, we can set up equation.

3x+1+2x+2+2x+2=180

Now combine like terms

7x+5=180

Then solve, first subtract 5 from both sides.

7x=175

Now divide 7 from both sides

x=25
