Since the shape is a square the sides are equal. Then we need to find x such that x * x = 169.
Sqrt(169) = 13
So x = 13
Answer:
58.1 and 31.9 degrees
Step-by-step explanation:
x + other angle = 90 because complementary angles add up to 90
x = the angle
x = 26.2 more than the other angle
subtract 26.2 from both sides
x - 26.2 = other angle
x + other angle = 90
plug x - 26.2 for other angle
x + (x-26.2) = 90
2x - 26.2 = 90
add 26.2 to both sides to isolate the variable and its coefficient
2x = 116.2
divide both sides by 2 to find x
x = 58.1
other angle = x - 26.2 = 31.9
Answer:
1) m<BFD is a triangle
2) AC is a line segment
Step-by-step explanation:
values that are <u>excluded from the domain</u> of a rational expression are values that make the denominator 0, since if that's so, the rational will be undefined. That happens when the denominator is zero out, let's do so
so, if ever m = 0, the denominator will become 0 and the rational becomes undefined, and whenever n = -3, the same will happen to the rational, thus those values are excluded.
Current density of solution a/m2 is given below
Step-by-step explanation:
Current density is the measure of current generated per unit surface area of electrode.
Eg: In microbial fuel cell/fuel cells, if you are using electrode with size of 5cm x 2cm and current produced is 200mA, then current density will be,
CD= Current/(projected area of electrode)
area of rectangle= LxB= 5cm x 2cm =10cm2
CD= 200mA/10cm2
CD= 20mA/cm2
Your Current will be 200mA.
Current density will be 20mA/cm2.
