What is the value of 30^0?

ElenaW [278]

Answer:

Value is 1.

Step-by-step explanation:

To find the value of $30^0$

$\text{Any number raised to the power of zero}$ is always equal to 1, but if zero to the power 0 is not defined.

Or simply we say that:

$\text{Any non-zero number raised to the power of zero}$ is always equal to 1

Here,

A non-zero number = 30 ≠0

then;

by definition:

$30^0 = 1$

Therefore, the value of $30^0$ is 1

If < D is a right angle and < E is a right angle, and you said that < D is congruent to < E, the reason would be ___

SVEN [57.7K]

Answer:

(B)All right angles are congruent

Step-by-step explanation:

Given that:

$\angle D$ is a right angle, and\\\angle E$ is a right angle\\\\\angle D=90^\circ\\\angle E=90^\circ\\$Therefore: \angle D \cong \angle E$

The reason for this congruency is that both are right angles and in fact, all right angles are congruent.
