Two ways:
Step-by-step explanation:
1. First way. Using the trig unit circle.
tan (pi - x) = - tan x
2. Second way. Apply the identity:
tan(a-b)=tan a- tan b/ 1 - tan a×tan b
tan (π - x)= tan π - tanx/1 - tan(π)×tanx
Since tan (pi) = 0, therefor:
tan(π−x)=−tanx
Answer:
-35-18x
Step-by-step explanation:
just calculate the difference
-35-20x+2x
-35-18x
Answer:
15187.5=2000(1.5)^5
Step-by-step explanation:
So right now he has 2000 in his saving each year it grows by 1.5 so by year 5 it should be
15187.5 in his savings
hope I did it right
Answer:
A
15:20
Step-by-step explanation:
Answer:
x=5√2
Step-by-step explanation:
This is a right isosceles triangle, so the base and leg are the same. Both are x.
Pythagorean Theorem:
x²+x²=10²
2x²=100
x²=50
x=√50
x=5√2
