Find the value of x.

X = 83

Step-by-step explanation:

Because we know that all angles of a triangle will equal 360 degrees we can set all three angles equal t0 360

To solve:

x + 64 + x+ 85 + 45 = 360

step 1: combine like terms

2x + 194 = 360

Step: subtract 194 from both sides

2x = 166

Step 3: divide both sides by 2

x = 83

you need to give us more information since we can't answer

60: 45 =12: 9 =4: 3 so the answer is 4: 3
