Step-by-step explanation:
hello :
tanx = √3 0°≤x≤360°
x = 60°
x=240°
Answer:
18°
Step-by-step explanation:
1. ∠A and ∠B are complementary angles, so they add up to 90°.
- This means that 2x - 4 + 5x + 17 = 90
2. To find the measure of ∠A, we first have to solve for x.
3. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 13 from both sides.
Step 3: Divide both sides by 7.
4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.
Therefore, the measure of ∠A = 18°.
Answer:
x = ± 3, x = ± 2i
Step-by-step explanation:
Given
f(x) = (x² + 4)(x² - 9)
To find the zeros let f(x) = 0, that is
(x² + 4)(x² - 9) = 0
Equate each factor to zero and solve for x
x² - 9 = 0 ( add 9 to both sides )
x² = 9 ( take the square root of both sides )
x = ± = ± 3
x² + 4 = 0 ( subtract 4 from both sides )
x² = - 4 ( take the square root of both sides )
x = ± = ± = ± × = ± 2i
Thus zeros are
x = - 3, x = 3 ← real
x = - 2i, x = 2i ← complex
