Answer:
8.4 (42/5)
well you know that 1/4 as a decimal is .25 so take the 5 and put it in front of the .25, so you will have 5.25. And 5/8 as a decimal is .625. then just divide them by using long division or a calculator.
An = -15 + 9(n - 1), since the first term is 15 and for each consecutive term we are adding 9 to the previous term
Answer:
$14.85
Step-by-step explanation:
99 x 85% = 84.15
99-84.15 = 14.85
Scalene triangle since all 3 interior angles are different values.
Answer:
Step-by-step explanation:
Tan 145 = - 0.7002
Tan 85 = 11.43
Tan 145 + tan 85 = 10.7298
1 - tan(145)* tan(85) = 9.003
(Tan(145) + Tan(85)) / (9.003)
= 10.73 / 9.003
= 1.1918
I misread the question. If you mean
(Tan145+tan85) /1-tan145*tan85 (brackets are really important here)
then the answer is
Tan(145 + 85)
= Tan(230)
= 1.1918
