Answer:(√x+√2)²=x+√x*2+2
(√x-2*√2)*(√x+2*√2)=x-8
Step-by-step explanation:
<h2>(√x+√2)²= √x²+2*√x*√2+√2²²=x+√x*2+2</h2><h2 /><h2>(√x-2*√2)*(√x+2*√2)=(√x)²-(2√2)²=x-8</h2>

Step-by-step explanation:
For the given triangle, the tan of angle A equals C.
.
Step-by-step explanation:
Step 1; In the given triangle, the opposite side has a length of 15 units, the adjacent side has a length of 36 units while the hypotenuse of the triangle measures 39 units. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.
cos A =
.
Step 2; The opposite side's length = 15 units,
The adjacent side's length = 36 units.
cos A =
, dividing the numerator and the denominator by 3, we get
cos A =
, which is option C.
