Answer:

x = 50.8°

Step-by-step explanation:

We are given:

1.) Angle x

2.) Side opposite to angle x

3.) Hypotenuse

Therefore to find the angle x, we will use the sin inverse:

<em>Sin(x) = Opposite / Hypotenuse</em>

Sin(x) = 6.2/8

x = Sin⁻¹(6.2/8)

Zinaida [17]

The irrational numbers are: √8, √10 and √15

Step-by-step explanation:

A rational number is a number that can be written in the form p/q where p&q are integers and q≠0.

"All the numbers whose square root is not a whole number and has an infinite number of digits after decimal, are irrational numbers"

So in the given options

$\sqrt{4} = 2$

Which can be written in the required form so √4 is a rational number

$\sqrt{8}=2.828427124746190097603.....$

√8 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

$\sqrt{10}=3.16227766016837933....$

√10 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

$\sqrt{15}=3.87298334620.....$

√15 has an infinite expansion hence it cannot be written in the p/q form, so it is an irrational number

$\sqrt{36} = 6$

Which can be written in the required form so √36 is a rational number

Hence,

The irrational numbers are: √8, √10 and √15

Answer:

Step-by-step explanation:

The solution to these two graphs will be when they are equal. Therefore:

$x^3+3=x^2+2 \\\\x^3-x^2+1=0 \\\\x\approx -0.755\approx -\dfrac{13}{16}$

Hope this helps!

A circle is centered on point B. Points A, C and D lie on its circumference.

IRISSAK [1]

Given:

A circle is centered on point B.

Points A, C and D lie on its circumference.

If $m\angle ABC$ measures 40°.

To find:

The $m\angle ADC$ .

Solution:

Central angle theorem: According to this theorem, the central angle is equal to the twice of inscribed angle on the same intercepted arc.

In the given figure $\angle ABC$ is the central angle and $m\angle ADC$ is the inscribed angle on the same arc AC.

Using central angle theorem, we get

$m\angle ABC=2m\angle ADC$

$40^\circ=2m\angle ADC$

$\dfrac{40^\circ}{2}=m\angle ADC$

$20^\circ=m\angle ADC$

Therefore, the measure of angle ADC is 20°.
