Answer:
x= 28
Step-by-step explanation:
The angles both sum up to 180°. So, the equation would be: 39+(5x+1)= 180.
Step 1- Add common numbers.
(39+1)+5x= 180
40+5x= 180
Step 2- Subtract 40 to both sides.
40+5x= 180
-40 -40
5x= 140
Step 3- Divide both sides by 5.
<u>5x</u>= <u>140</u>
5 5
x= 28
Answer:
<u>The correct answer is C. 9 -√ 105/ 2, 9 + √ 105/ 2</u>
Step-by-step explanation:
Let's find the solutions for the quadratic equation:
x² = 9x + 6
x² - 9x -6 = 0
Using the quadratic formula, we have:
x = [- (-9) +/- √ (-9)² - 4 * 1 * -6]/2 * 1
x = [ 9 +/- √ (81 + 24]/2
x = [ 9 +/- √ (105]/2
x₁ = [ 9 + √ (105]/2
x₂ = [ 9 - √ (105]/2
<u>The correct answer is C. 9 -√ 105/ 2, 9 + √ 105/ 2</u>
Note: Same answer than question 14133688, answered by me today.
This is not possible. False.
(BLASPHEMY I SAY!)
Answer:
I dont no :)
Step-by-step explanation:
lol
The solution would be like this for this specific problem:
sin(θ°) = √(2)/2
θ° = 360°n + sin⁻¹(√(2)/2) and θ° = 360°n + 180° −
sin⁻¹(√(2)/2)
θ° = 360°n + 45° and θ° = 360°n + 135° where n∈ℤ
360°*0 + 45° = 45°
360°*0 + 135° = 135°
360°*1 + 45° = 405°
<span>sin(225°) = -√(2)/2
</span>225 has an angle where sin theta= -(sqrt2)/2 therefore, the value of theta
cannot be 225 degrees.
