Answer:

$\frac{5\pi-6 }{10}$

Step-by-step explanation:

We know -pi/2 < x < pi/2

We also know that a = arcsin(b)

so sinx = cos3/5

We will then be left with (5pi-6)/10 in radians, or 55 degrees

Best of luck

How did he get this 1/2i ? I dont remember studying this definition in calc 1 neither calc 2!

Hitman42 [59]

The $i$ in the denominator is missing in the second expression. It should be

$\sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$

This follows from

$e^{iat}=\cos at+i\sin at$
$e^{-iat}=\cos at-i\sin at$
$\implies e^{iat}-e^{-iat}=2i\sin at$
$\implies \sin at=\dfrac{e^{iat}-e^{-iat}}{2i}$

Pls help me with this!

Answer:

See below.

Step-by-step explanation:

(a) < PMR

(b) < QMR

(d) < RMN

2. m < C = 4x - 6

= 4(25) - 6

= 100 - 6

= 94 so < C is obtuse.

3. 8x + 2 = 90

8x = 90 - 2

8x = 88

x = 11.

(a). < DBA and < DBC are right angles (90 degrees) because BD is perpendicular to AC.

(b) < DBA and < DBC are adjacent and they share the ray BD.

(d) < DBA and < DBC are supplementary

(e) 90 - 40 = 50 degrees

(f) 180 - 40 = 140 degrees.

(g) As the angles are complementary

3x + 2 + 4x + 4 = 90

7x = 90 - 2 - 4

7x = 84

x = 12.
