How do you solve for X and round the nearest tenth​

Mathematics

Answer:

x = 7.3

Step-by-step explanation:

When solving for missing sides using angles, use trig functions.  

We have the angle 63° to use.  

We are given the hypotenuse of the triangle, as well as the side adjacent to the angle, so we can use the cos function.

Cos T = (adjacent side)/(hypotenuse)

Here we know 'T' and the hypotenuse, so plug them in and solve

Cos 63° = x/16

  (16)Cos 63° = x    (multiply both sides by 16 to isolate 'x')

      7.263847996 = x           (use your calculator to solve the left side)

      7.3 = x   (rounded to the nearest 10th)

The cosine of A is (adjacent side)/(hypotenuse) = 55/73. Do the division, then find the angle whose cosine is that number. The whole thing takes maybe 6 or 7 seconds with your calculator. It's choice-B.

Which values of x and y would make the following expression represent a real number? (4 + 5i)(x + yi)
Verizon [17]
4 (x + yi) +5 (x + yi)
(4x + 4yi) + (5x + 5yi)
4x _5x +4yi _5yi
_1x + _1yi
therefore x= _1
