If m<TUV = (9x + 1), m<TUW = (7x-9), and m<WUV = (5x - 11), find the value of x.

x = 7

Step-by-step explanation:

Suppose ray UW divides ∠TUV into two angles ∠ TUW and ∠ WUV.

Then, m∠TUV  = m∠ TUW + m ∠ WUV               (i)

Given,  m∠TUV  = (9x + 1) , m∠ TUW =  (7x-9) and m ∠ WUV = (5x - 11)

Substitute these values in (i), we get

Hence, the value of x = 7.

i belive those are the ones that are under 90 degreese.

just get this app called photo math it should be able to do those
