Find x if cos(x)=.1412

2 answers:

8 0

To find the value of an angle X, you need to divide both sides of the equation by cosine to isolate x. This would give you cos-1 (inverse cosine or secant) equals .1412. Then you can use a calculator to evaluate, making sure that it is in degrees, not radians. The cos-1(.1412) is approximately 81.88270898

sashaice [31]

Answer:

the first number is 5 the second number is 4

Step-by-step explanation:

first number = x

second number = y

X+2y=13 given this isolate x x = 13-2y

2x+y=14 substitute 13-2y for x

2(13-2y)+y=14

26-4y+y=14

-3y=-12

y=4 taking this number substitute into either equation above

x+2(4)=13

x+8=13
