(sin30° + cos30°) – (sin 60° + cos60°)​

Mathematics
1 answer:
Darya [45]3 years ago
8 0

Answer:

0

Step-by-step explanation:

Sin 30° = ½

Cos 30° = √3/2

Sin 60° = √3/2

Cos 60° = ½

Therefore,

(½ + √3/2) - (√3/2 + ½)

\frac{1 +  \sqrt[]{3} }{2}  -  \frac{ \sqrt{3 + 1} }{ 2 }

\frac{1 +  \sqrt{3}  -  \sqrt{3}  -  1}{2}

\frac{0 - 0}{2}

Answer: 0

-3(-4n + 30) = -30 need help​
DIA [1.3K]

First we will do -3 times everything in the parenthesis.

-3 times -4n = 12n

-3 times 30 = -90

SO,

12n - 90 = -30

       +90    +90

12n = 60

divide 12 on both sides;

n = 5
