Answer:
sin²x
Step-by-step explanation:
we have
(1 − cos x)(1 + cos x)=1-cos²x
Remember that
sin²x+cos²x=1 ------> i-cos²x=sin²x
therefore
(1 − cos x)(1 + cos x)=sin²x
Do 45/225 and simplify and that’s your answer
Answer:
A = 110 degrees.
Step-by-step explanation:
< A and < B are same side angles so their values add up to 180 degrees, so:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 252
x = 18.
So m A = 5(18) + 20
= 110 DEGREES.
basicly it is addition add 50 cent 4 times then add the dolars to that witch will get you to 6.00 bucks add the taxes witch is 5 bucks and 50 cent so 10.50 is your ansewer
