Answer:
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
