Answer:

You can use the factoring process

Step-by-step explanation:

To solve a quadratic equation by factoring,

Put all terms on one side of the equal sign, leaving zero on the other side.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation.

Example 1

Solve x 2 – 6 x = 16.

Following the steps,

x 2 – 6 x = 16 becomes x 2 – 6 x – 16 = 0

Factor.

( x – 8)( x + 2) = 0

In this question, I’m supposed to use sin instead of tan. But the question is worded weirdly. How can I know that I’m suppose to

zhannawk [14.2K]

Answer:

Since the kite is flying, the hypotenuse side of the triangle is 32.4m, while the adjacent side is unknown.

Given the opposite and hypotenuse, we use sine to find the angle.

$\boxed{sinθ = \frac{opp}{hyp} }$

$sinθ = \frac{18.3}{32.4}$

$θ = {sin}^{ - 1} ( \frac{18.3}{32.4} )$

θ= 34.4° (1 d.p.)

Thus, the angle the kite string makes with the ground is 34.4°.

Notes:

$cosθ = \frac{adj}{hyp}$

$tanθ = \frac{ opp}{adj}$

Answer:

a. 146

Step-by-step explanation:

{4*[72-6*(3+2)]}-22

=[4*(72-6*5)]-22

=[4*(72-30)]-22

=(4*42)-22

=168-22

=146
