Step-by-step explanation:
Simplifying
3x + -28 + 3x + -30 + x = 33
Reorder the terms:
-28 + -30 + 3x + 3x + x = 33
Combine like terms: -28 + -30 = -58
-58 + 3x + 3x + x = 33
Combine like terms: 3x + 3x = 6x
-58 + 6x + x = 33
Combine like terms: 6x + x = 7x
-58 + 7x = 33
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '58' to each side of the equation.
-58 + 58 + 7x = 33 + 58
Combine like terms: -58 + 58 = 0
0 + 7x = 33 + 58
7x = 33 + 58
Combine like terms: 33 + 58 = 91
7x = 91
Divide each side by '7'.
x = 13
Simplifying
x = 13
AnswerSolving
-58 + 7x = 33

Answer:
a = 1√6
b = -2
Step-by-step explanation:
Hello,
To solve this trigonometric problem, we need to convert this values into fractions
a).
Sin45° = 1/√2
cos30° = √3/2
Sin60° = √3/2
Sin45° / (cos30° + sin60°) = [(1/√2) ÷ (√3/2 + √3/2)]
(1/√2) ÷ (√3/2 + √3/2)
Add √3/2 + √3/2
1/√2 ÷ 2√3/2
1/√2 × 2/2√3
2/2√(2×3)
2/2√6
1/√6
b
Cos 180° = -1
Sin150° = ½
Tan135° = -1
2cos180° - 2sin150° - tan135°
(2 × -1) - (2×½) - (-1)
-2 - 1 + 1 = -2
