Answer:

θ = 37°

Step-by-step explanation:

The missing angle is θ

cos θ = 4/5

cosθ = 0.8

Using a calculator:

cos^(-1)(0.8) = 36.86≈ 37°

so θ = 37°

Deffense [45]

Answer:

Value of x will be 0.1515

Step-by-step explanation:

We have given the equation $4e^{2x}-3-5=0$

We have top fond the value of x using exponent and logarithmic property

So $4e^{2x}-3-5=0$

$4e^{2x}-8=0$

$4e^{2x}=8$

$e^{2x}=2$

Taking log both side

$lne^{2x}=ln2$

$2x=0.3010$

x = 0.1515

Aleks [24]

Answer:

<CPB

Step-by-step explanation:

Because <APE= right angle

<APC= Obtuse angle

<CPE= Obtuse Angle.

Also, <CPB because its the only angle below 90 degrees and an acute angle must be below 90 degrees.
