Answer:

$z=68$

Step-by-step explanation:

Use the formula $180\times(n-2)$ to find the sum of the angles in a polygon, given n sides. This formula tells us the angles of this pentagon must add to 540 ( $180\times(5-2)=540$ ).

So, we can setup an equation:

$70+2z+11+119+z+2z=540$

Solve for z:

$200+5z=540$ Combine like terms

$5z=340$ Subtract 200

$z=68$ Divide by 5

Therefore, the value of z = 68.

Answer:

260π in²

Step-by-step explanation:

The slant height is the hypotenuse of a right triangle with legs 10 and 24. Using the Pythagorean theorem, we find it to be ...

l² = 10² +24² = 100 +576 = 676

l = √676 = 26

The given formula tells you the lateral area is ...

A = πrl = π(10 in)(26 in)

A = 260π in² . . . . . cone's lateral area

Additional comment

The name of the constant relating diameter to circumference (π) is "pi". It is the 16th letter of the Greek alphabet. "Pie" is something else entirely.

Given: circle k(O), m∠P=95°, m∠J=110°, m∠LK=125° Find: m∠PJ

IRINA_888 [86]

Answer:

The measure of the arc PJ is $75\°$

Step-by-step explanation:

step 1

Find the measure of angle L

we know that

In a inscribed quadrilateral opposite angles are supplementary

$m$

we have

$m$

substitute

$m$

step 2

Find the measure of arc KJ

we know that

The inscribed angle measures half that of the arc comprising

$m$

substitute the values

$95\°=\frac{1}{2}(125\°+arc\ KJ)$

$190\°=(125\°+arc\ KJ)$

$arc\ KJ=190\°-125\°=65\°$

step 3

Find the measure of arc PJ

we know that

The inscribed angle measures half that of the arc comprising

$m$

substitute the values

$70\°=\frac{1}{2}(65\°+arc\ PJ)$

$140\°=(65\°+arc\ PJ)$

$arc\ PJ=140\°-65\°=75\°$

I’m so stupid I don’t know

adell [148]

Answer:

I am stupid too, so forgive me if I am wrong.ಥ_ಥ

I am pretty sure the correct answer is D since 2 can be multiplied by 3 to get 6, and 3 can be multiplied by 3 to get 9. Thus, if the number of guitars is multiplied by 3, the number of amps will always be a multiple of 3.
