Solve the trigonometric equation √2 cos − 1 2 cos + 1 = 0 in the interval [0, 360°). find the exact values of the solutions in d

Elena-2011 [213]

Assuming cos means cos(x);

Combine all like terms: cos(x)(√2 - 12)= -1
Isolate x: cos(x)= -1/(√2 - 12)

cos(x)=0.0944
x=cos⁻¹(0.0944)
x= 84.57 degrees or (360-x=275.42 degrees)

Hope I helped :)

The sum of two numbers is 48.<br>the second number is seven times the first number

dusya [7]

Answer:

$\huge\boxed{\sf x =6,\ y = 42}$

Step-by-step explanation:

Let the numbers be x and y

<h3>Given condition:</h3>

x + y = 48 --------(1)

y = 7x -------------(2)

Put Eq. (2) in (1)

x + 7x = 48

8x = 48

Divide 8 to both sides

x = 48/8

Put x = 6 in Eq. (2)

y = 7 (6)

$\rule[225]{225}{2}$
