An angle measures 3.2° less than the measure of its complementary angle. What is the measure of each angle?

cupoosta [38]

Answer:

Step-by-step explanation:

x - measure of angle

x + 3.2° - measure of its complementary angle

Complementary angles adds to 90°

x + x + 3.2° = 90°

2x = 90° - 3.2°

2x = 86.8°

x = 86.8°÷2

x = 43.4°

x+3.2° = 43.4° + 3.2° = 46.6°

Answer:

$-\cos nw_0t$

Step-by-step explanation:

We can use the double angle identity for sine.

$\sin (A+B)=\sin A \cos B+\sin B\cos A$

The given expresion is

$\sin (nw_0t-90)$

We apply the identity to get:

$\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90$

We simplify to obtain;

$\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)$

This simplifies to:

$\sin (nw_0t-90)=-\cos nw_0t$ The correct answer is D

18 2by5-4 1by10 find the difference

luda_lava [24]

Given:

The expression is:

$18\dfrac{2}{5}-4\dfrac{1}{10}$

To find:

The difference.

Solution:

We have,

$18\dfrac{2}{5}-4\dfrac{1}{10}$

It can be rewritten as:

$=\dfrac{90+2}{5}-\dfrac{40+1}{10}$

$=\dfrac{92}{5}-\dfrac{41}{10}$

Taking LCM, we get

$=\dfrac{184-41}{10}$

$=\dfrac{143}{10}$

$=\dfrac{140+3}{10}$

$=14\dfrac{3}{10}$

Therefore, the value of the difference is $14\dfrac{3}{10}$ .
