8x-28-2x=-10
10x-28=-10
10x=18
x=1.8

8x-28-2x=-10
Add 28 to each side to get all the x's on one side by themselves:
8x-28-2x=-10
8x-2x=18
Simplify the left side:
8x-2x=18
6x=18
Divide each side by 6 to get the value of one individual "x":
6x/6=18/6
x=3

Plzz help <br><br>find value of following : 2sin75°.cos15°

polet [3.4K]

Answer:

$\frac{2+\sqrt{3} }{2}$

Step-by-step explanation:

Using the product to sum formula

sinxcosy = $\frac{1}{2}$ [ sin(x + y) + sin(x - y) ] , then

2sinxcosy = sin(x + y) + sin(x - y)

Given

2sin75°cos15° ← with x = 75 and y = 15 , then

= sin(75 + 15) + sin(75 - 15)

= sin90° + sin60°

= 1 + $\frac{\sqrt{3} }{2}$

= $\frac{2+\sqrt{3} }{2}$
