Answer:

$x\approx 63.4^0$

Step-by-step explanation:

In the given right triangle,

Measure of angle = x°

Opposite side of the angle = 12 units

Adjacent side of the angle = 6 units

By taking tangent ratio of the given angle,

tan(x°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{12}{6}$

= 2

$x^0=\text{tan}^{-1}(2)}$

$x=63.43^0$

$x\approx 63.4^0$

Line A. C. D. B. Defined Postulates Theorems Undefined Terms

oksian1 [2.3K]

Answer: Undefined

Step-by-step explanation:

In geometry there are three undefined terms that we use to define other terms:

Point → In geometry a point has a location but no dimension.
Plane → A plane extends is a 2-dimensional surface that extends infinitely on both sides.
Line → A line is a one-dimensional undefined figure that extends infinitely in both the directions. It has length but has no width.

Hence, the correct option is "Undefined".
