The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.

<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>

If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.

Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.

Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.

Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.

When a number is decreased by 2.6%, the result is 83. What is the original number to the nearest tenth?
slavikrds [6]

Answer:

The original number is 85.2

Step-by-step explanation:

we can represent this in an equation where the initial value is going to be and to this we will subtract 2.6% of it

x - x * 2.6/100 = 83

x - 0.026x = 83

0.974x = 83

x = 83 / 0.974

x = 85.2156

we round to the nearest tenth and finally we get that the result is 85.2

if we want to verify that it is ok we can replace the x with the value of 85.2156 and we should have the same number on each side of the equality

Here is the definition of a negative exponent.

For any non-zero value of a,

a^{-n} = \dfrac{1}{a^n}

Look at your problem and follow the definition.

4^{-3} = \dfrac{1}{4^3}

Since 4^3 = 4 * 4 * 4 = 64, we can now write:

4^{-3} = \dfrac{1}{4^3} = \dfrac{1}{4 \times 4 \times 4} = \dfrac{1}{64}
