Hello!
Let's write this as an equation.
3(x+3)=5x-3
First, let's simplify the parentheses.
3x+9=5x-3
Let's subtract 5x from both sides.
-2x+9=-3
We subtract 9 from both sides.
-2x=-12
We divide both sides by -2.
x=6
Therefore, the number is 6.
I hope this helps!
The answer would be tan (44).
For sin (75)
The answer will be computed this way:
sin 75º = sin (30)º + 45º= sin 30 cos 45+cos 30 sin 45= 1/2*√2/2+√3/2*√2/2=√2/4+√6/4=(√2+√6)/4Check with calculator:sin 75º ≈ 0.9659
For tan (44): checking with the calculator the answer is also: ≈ 0.9659
Answer:
an=a1+d(n−1) a n = a 1 + d ( n - 1 )
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding −5 to the previous term in the sequence gives the next term. In other words, an=a1+d(n−1) a n = a 1 + d ( n - 1 ) .
Answer:
The sum of the angles in any triangle is 180 degrees. If one of the three angles is 90 degrees (a right angle) the the sum of the other two angles is 90 degrees. Therefore each of the other two angles must be acute.
The statement is TRUE.
