Answer:
- 22.5
Step-by-step explanation:
Answer:
90 decreased by 25% = 67.5
Absolute change (actual difference):
67.5 - 90 = - 22.5
If the triangle has a right angle, the measure of the third side is 12.8 inches
I=Prt
I=500*0.02*4
I=$40
So, basically the answer is $40.
Answer:
Step-by-step explanation:
I assume that you mean
sec(x)-tan(x) = 1 / ( sec(x) + tan(x) ) , right ?
then this is equivalent to
[ sec(x) - tan(x) ] x [ sec(x) + tan(x) ] = 1
let s evaluate it, we got
sec2(x) - sec(x)tan(x) + - sec(x)tan(x) - tan2(x) = sec2(x) - tan2(x)
= (1 - sin2(x) ) / cos2(x) = cos2(x) / cos2(x) = 1
as cos2(x) + sin2(x) = 1
50*8=400
400+175=575
it subtracted 575 on the last round
