1. sin(x+20) = cos(2x+10)<br> 2. sin (2x+14) = cos(x-5)
lakkis [162]

Answer:

x=20°

2.

x=27°

Step-by-step explanation:

sin(x+20)=cos (2x+10)

=sin (90-(2x+10))

so x+20=90-(2x+10)

x+20+2x+10=90

3x=90-30

3x=60

x=60/3=20

2.

2x+14+x-5=90

3x+9=90

3x=90-9=81

x=81/3=27

what is the algebraic equation product of 3 and a squared number is twice the sum of the number and 4
Katyanochek1 [597]
Let n = number

" product of 3 and a squared number" translates to 3n²

"sum of the number and 4" translates to n + 4

The word "is" becomes your equals sign. 

3n² = n + 4 is your equation.
