You can either do it to the nearest ten or the nearest hundred
(nearest ten) 590 - 320 = 270
(nearest hundred) 600 - 300 = 300
You could either:
a) Use the Pythagorean Theorem
b) Use Sine/Cosine/Tangent Inverse to find one of the angles, and then use that angle to find x.
Answer:
x = 0
Step-by-step explanation:
→ Expand out the brackets
6 - 18x + 4x - 6 = 0
→ Collect all the like terms
-12x = 0
→ Now solve
x = 0
