Can someone help me with these 2 questions. angle sum theorem

D. 8

Step-by-step explanation:

Total sum of angles in a triangle is 180

I'll do the first one, you can try the second

9x + 5 + 78 + 25 = 180

9x + 108 = 180

9x = 72

x = 8

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
