Try this option:
1. rule: cosα=sin(90°-α), it means that cos 3x=sin(90°-3x);
2. sin(90°-3x)=sin(x+18°); ⇔ 90°-3x=18°+x; ⇔ x=18°.
Answer: x=18°.
Answer:
250
Step-by-step explanation:
He saved 250 because
25% - 1000 = 250
Answer:
Step-by-step explanation:
we have
50%, 2/25, 5, and 0.31
1) 50%
we know that
2) 2/25
Multiply by 4/4
3) 5
Multiply by 100/100
4) 0.31
Multiply by 100/100
Now all numbers have the same denominator
so
therefore
