Answer:

10

Step-by-step explanation:

This is one of the easiest equations to perform on a calculator and to memorize, as I had to do in 7th grade. Just remember that when you multiply anything by 10, including itself, you just add a 0 to the result. So, 10 * 10 = 100. 10 * 11 = 110. 10 * 12 = 120. And so on...

The sum of the measures of the angles of any triangle is 180 degrees. In triangle ABC, angles A and B have the same measure, w

aniked [119]

Answer:

A=B

Hence A+81=C

Now let's rearrange:

3A=99

So A= 33

B=33

and C = 33+81= 114

Triangle KNM is isosceles, where angle N is the vertex.

Anika [276]

Answer:

25°

Step-by-step explanation:

In isosceles triangle KNM, NL is a perpendicular bisector of angle KNM.

This means

$m\angle KNL=m\angle LNM$

Since

$m\angle KNL=(5x+10)^{\circ}\\ \\m\angle LNM=(6x-1)^{\circ},$

you have

$5x+10=6x-1\\ \\5x-6x=-1-10\\ \\-x=-11\\ \\x=11$

No, find the measure of angles KNL and LNM:

$m\angle KNL=(5\cdot 11+10)^{\circ}=65^{\circ}\\ \\m\angle LNM=(6\cdot 11-1)^{\circ}=65^{\circ}$

and the measure of angle KNM is

$m\angle KNM=m\angle KNL+m\angle LNM=65^{\circ}+65^{\circ}=130^{\circ}$

Angles adjacent to the base of isosceles triangle are congruent. The sum of the measures of all interior angles is 180°, then

$m\angle K=\dfrac{1}{2}(180^{\circ}-130^{\circ})=25^{\circ}$

Find the surface area, in square centimeters, of

nydimaria [60]

The surface area of the hemisphere with radius r = 19 cm. is 3400.62 square centimeters

<h3>How to determine the surface area?</h3>

The radius is given as:

r = 19

The surface area of a hemisphere is:

Area = 3πr²

So, we have:

Area = 3 * 3.14 * 19²

Evaluate

Area = 3400.62

Hence, the surface area of the hemisphere is 3400.62 square centimeters
