Answer:

  1.1 ∠LKR = 90°

  1.2 ∠R = 32°

  1.3 ∠N = 32°

Step-by-step explanation:

1.1 An inscribed angle is half the measure of the arc it subtends. Angle LKR is half the measure of the arc of semicircle LNR, so is 90°.

  ∠LKR = 90°

__

1.2 ΔLKR is a right triangle with angles L1 = 58°, ∠K = 90°, so ∠R is ...

  ∠R = 90° -58°

  ∠R = 32°

__

1.3 ∠N subtends the same arc LK that ∠R does, so it has the same measure.

  ∠R = ∠N = 32°

The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is more than the measure of the smallest angle. Find all three measures .

Answers

Answer:

45degrees, 79egrees and 56degrees

Step-by-step explanation:

Complete question:

The measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle. The measure of the third angle is  11 more than the measure of the smallest angle. Find all three measures .

Let the smallest angle be x

Let the largest angle be y

Let the third angle be z

Since the sum of angle in the triangle is 180, then x+y+z = 180 .. 1

If the measure of the smallest angle of a triangle is 34 less than the measure of the largest angle of the triangle, this is expressed as;

x = y - 34

y = x + 34 ..... 2

If the measure of the third angle is  11 more than the measure of the smallest angle, this is expressed as;

z = x +  11 .... 3

Substitute 2 and 3 into 1;

x + (x+34) + (x+11) = 180

x+x+x+45 = 180

3x+45 = 180

3x = 180 - 45

3x = 135

x = 135/3

x = 45 degrees

From 2;

y = x+34

y = 45 + 34

y =79degrees

From3;

z = x+11

z = 45 + 11

z = 56degrees

Hence the measure of the angles are 45degrees, 79egrees and 56degrees

The length of a rectangle is units greater than twice its width. If its width is w, which expression gives the perimeter of the rectangle in terms of w?
A.
2(w) + w
B.
w + w
C.
3w +
D.
6w + 5

Answers

The expression which shows the perimeter in terms of w is option d which is 6w+5.

What is expression?

Expression is a combination of numbers, fraction, symbols, indeterminants, determinants,etc. It shows a relationship between two or more variables. It is mostly not found in equal to form.

How to find perimeter?

We have been given that width be w, so the length will be 2w+5/2.

We know that perimeter of rectangle is 2(l+b)

Perimeter=2(2w+5/2+w)

=2(3w+5/2)

=2(6w+5)/2

=6w+5

Hence the the expression which shows the perimeter of rectangle having width w and length is 5/2 units greater than double the width in terms of w is option d which is 6w+5.

Rafael is cutting pieces of wood to make a triangular pyramid like the one shown below. The base of the pyramid is an equilateral triangle, and the faces are isosceles triangles.

Answers

Answer:

[tex]Total = 32.4in^2[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

The surface area of the pyramid

To do this, we calculate the surface area of each of the pyramid faces.

For the equilateral triangle.

[tex]Base = 4.5in[/tex]

[tex]Height = 3.9in[/tex]

The area is:

[tex]A_1 = 0.5 * Base * Height[/tex]

[tex]A_1 = 0.5 * 4.5in * 3.9in[/tex]

[tex]A_1 = 8.775in^2[/tex]

There are 3 isosceles triangles of equal dimension.

[tex]Base = 4.5in[/tex]

[tex]Height = 3.5in[/tex]

The area of one of them is:

[tex]A_2 = 0.5 * 4.5in * 3.5in[/tex]

[tex]A_2 = 7.875in^2[/tex]

For the 3, the surface area is:

[tex]3A_2 = 7.875in^2 * 3[/tex]

[tex]3A_2 = 23.625in^2\\[/tex]

The total surface area is:

[tex]Total = 8.775in^2 + 23.625in^2[/tex]

[tex]Total = 32.4in^2[/tex]

Answers

Answer:

the angle closest to the 40degree angle is a right angle, so it is 90 degrees. The one with two lines is 50 degrees, and the farthest angle is 40 degrees

Step-by-step explanation:

A square symbol over an angle means it is a right angle, so it will always equal 90 degrees.

The already labeled angle (40 degrees) is equal to the farthest angle.

Once you have two angles, you can find the third angle by simply subracting the two from 180 like this:

180 - 90 - 40 = 50 degrees.

Answers

Answer:

w = 2√155 ft ✅

Step-by-step explanation:

Given that:

depth (d) = 10½ ft

Volume (v) = 6,510 ft³

Find the width (w) of the hole!

If the base is a square, then

the width and the length of the base is 'equal', so the

Volume of a cuboid =

V = w²d

width = square root of the division of volume by depth

w = √(V/d)

w = √(6,510/10½)

w = √620

w = √(4×155)

w = 2√155 ft ✅

Answers

Width of rectangle = x
Length =3x+7
Perimeter of rectangle = 158cm
2(l+w)=158
2(3x+7+x)=158
2(4x+7)=158
8x+14=158
8x=158-14
x=144/8
x=18
Therefore the width of the rectangle is 18cm
Length=3x+18+7
54+7=61cm
