Answer:

Therefore,

$AB=16.25\ units$

The Measurement of AB is 16.25 units.

Step-by-step explanation:

In Right Angle Triangle ABC

m∠C=90°

AC = 10.01 .....(Adjacent Side to angle A)

m∠A=52°

cos 52 ≈ 0.616

To Find:

AB = ? (Hypotenuse)

Solution:

In Right Angle Triangle ABC, Cosine Identity,

$\cos A= \dfrac{\textrm{side adjacent to angle A}}{Hypotenuse}\\$

Substituting the values we get

$\cos 52= \dfrac{AC}{AB}=\dfrac{10.01}{AB}$

But cos 52 ≈ 0.616 ....Given

$AB=\dfrac{10.01}{0.616}=16.25\ units$

Therefore,

$AB=16.25\ units$

The Measurement of AB is 16.25 units.

Which of the following expressions is the conjugate of a complex number with 2 as the real part and 3i as the imaginary part?

lbvjy [14]

The complex number is represented as 2 + 3i. The conjugate of the complex number is the number with equal real part and imaginary part equal in magnitude but opposite in sign. Therefore, the correct answer is option B. The conjugate of the complex number is 2 − 3i.
