I NEED HELP PLEASE, THANKS! :)
Allushta [10]

Answer:  proof below

<u>Step-by-step explanation:</u>

Use the Difference formula for sin:

  sin (A - B) = sin(A)·cos(B) - cos(A)·sin(B)

sin (180° - θ) = sin(180°)·cos(θ) - cos(180°)·sin(θ)

                    =       0  · cos(θ)    -      -1  · sin(θ)

                    =              0           -           -sin(θ)

                    =                         + sin(θ)

sin (180° - θ) = sin(θ)  \checkmark

Find the length of side x I simplest radical form​
alekssr [168]

Answer:

Option A

Step-by-step explanation:

By applying Pythagoras theorem in ΔABC,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

AC² = AB² + BC²

AC² = 6² + 5²

AC = \sqrt{61}

Similarly, by applying Pythagoras theorem in ΔACD,

AD² = AC² + CD²

(10)² = (\sqrt{61})^2 + x²

x² = 100- 61

x² = 39

x = √(39)

Option A will be the answer.
