Find Sin 2 (30degrees)

Vinvika [58]

Answer:

Sin 2 (30)°= $\frac{\sqrt{3} }{2}$

Step-by-step explanation:

Explanation:-

Given that Sin 2 (30)°

we know that the formula sin2θ = 2sinθ cosθ

Given that θ = 30°

Now

sin2(30)° = 2sin30° cos30°

$= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )$

After cancellation, we get

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

Final answer:-

Sin 2 (30)° = $\frac{\sqrt{3} }{2}$

(SAT Prep) Find the value of x.

AveGali [126]

Answer:

x = 155

Step-by-step explanation:

First find the missing angle in the smaller triangle.

We know that the sum of the angles in a triangle is 180 so 35 + 90 + the missing angle = 180 so 180 - (35+90) = 180 - 125 = 55

Since the line above is a straight line, the sum of the angles must equal 180 so 55 + 60 + ? = 180. So 180 - 115 = 65.

The triangle is a right triangle so that means on of the angles is 90. So 65 + 90 = 155, so we have 180 - 155 = 25.

The angle that x is on is also a straight line so that means the angles must add up to 180 so 180 - 25 = 155.
