Answer:

x = -1

Step-by-step explanation:

Since a triangle's angles all add up to 180 based on this formula: 180(n-2) (n being the # of sides of the shape you're solving for, and the total being the interior), we can set up this equation:

46 + (x+62) + 73 = 180

Now, we can solve for x:

x = 180-73-62-46

x = -1

The values of ∠T is 18.78 degree.

In ΔSTU ,

We have:

T = 390 cm,

S = 900 cm

and ∠S=48°.

Using the sine rule which works law of sin with the formula:

[tex]\frac{SinT}{T} = \frac{SinS}{S}[/tex]

Plug all the values in above formula:

sinT/ 390 = sin48°/900

sin T = 0.743 × 390 / 900

sin T = 0.3220

T = [tex]sin^-^1[/tex](0.3220)

T = 18.78 degree.

Hence, The values of ∠T is 18.78 degree.

The height of the cone is about 15.9 meters.

The hypotenuse of the right triangle, which also contains the cone height as one of its legs, is formed by the radius (18 m) and slant height. You may find out the height (h) using the Pythagorean theorem.

The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, a2 + b2, are equal to the squares on the legs.

So,

 18² + h² = 24²

  h = √(576 -324) = √252

The third angle of the triangle must have a measure of 180° minus the sum of the other two angles, which is 180° - (46° + 73°) = 61°. Therefore, the measure of the missing angle is 61°.

The internal angles of a triangle are measured in degrees and are known as triangle angles. The sum of a triangle's angles is always 180°.

Triangle angles are classified into three types: acute angles, right angles, and obtuse angles.

An acute angle is one that is smaller than 90 degrees. This is the most common form of angle in a triangle and is regarded the most desirable.

A right angle is one that is exactly 90 degrees. This sort of angle is the most stable and sturdy in a triangle, therefore it is usually employed to make a triangle.

An obtuse angle is one that is larger than 90 degrees but less than 180 degrees. This form of angle is common in triangles, however it is less desirable than an acute angle.

The sum of the three angles of a triangle is always 180°. Acute angles are the most desirable and stable, whereas obtuse angles are present in certain triangles but are not as ideal.

In the given question,

The measure of the missing angle is 180° - (46° + 73°).

180° - (46° + 73°) = 180° - 119° = 61°

Therefore, the measure of the missing angle is 61°.

Answer:1.25(400)

Step-by-step explanation:

The two different possible values for height h and radius r for the cones are height = 3 inches when radius = 3 inches and height = 4.5 inches when radius = 2 inches.

The volume of a cone is given by the formula [tex]V = (1/3)\pi r^2 h[/tex].

We can use this formula to find the values of h and r that will give us a cone with a volume of 9π cubic inches.

We have a volume of the cone -

(1/3)π[tex]r^2[/tex]h = 9π

solving for h, we get,

h = (3/[tex]r^2[/tex]) * 9

Now we have a formula for h in terms of r. We can substitute different values for r and see what values of h we get. Let's consider two possibilities:

                   h = (3/[tex]3^2[/tex]) * 9 = 3 inches

                   h = (3/[tex]2^2[/tex]) * 9 = 4.5 inches

So, one possible cone has a height of 3 inches and a radius of 3 inches, and another possible cone has a height of 4.5 inches and a radius of 2 inches.

Every relationship that always maintains the same ratio is referred to be proportionality. For instance, the average amount of apples per tree determines the proportionality between both the quantity of apples in a crop and the number of trees in the orchard.

Let the amount a tree grows in one month be - x

Step-by-step explanation:

you make 7% of 100 multiply by $275 and the price that gives you you make more $275 and that gives you your results

Answer:

x= 4/3

Step-by-step explanation:

Think the negative sign outside the parentheses as -1. Then do distributive property to the numbers inside the parentheses.

-1 x 3x and -1 x -12

That equals to -3x + 12 so now your entire equation is -3x + 12 = 9x - 4. Now lets take away 9x from both sides like this,

9x - 9x and -3x - 9x.

That equation is now -12x + 12 = -4.

Now subtract 12 from both sides like this,

12 - 12 and -4 - 12.

And then you have -12x = -16.

Now you divide both numbers by -12 like this,

-12x/-12 which equals to just x and then do -16/-12 which would equal as 1.3333 and repeating but, it can be put as 4/3 for a clearer answer.

Three lots with parallel side boundaries extend from the avenue to the boulevard.

x + y + z = 140 meters

According to the proportion theorem,

Solving for x, using cross multiplication:

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40

z = 7x/8

Now, the third proportions,

y/30 = z/35

Solving for y,

y = 30z/35

y = 6z/7

x + y + z = 140

4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substituting z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520

Now,

Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,

We know that

y = 3x/4

so,

y = 40

The perimeter of triangle XYZ is 38.95 inches

Consider the following figure.

The area of rectangle WXYZ is 115. 5 in.²

From given figure we can observe that PQ = 4 in.

So, XW = YZ = 2 × PQ

XW = YZ = 2 × 4

XW = YZ = 8 inches

This means, the width of rectangle WXYZ is  8 inches

We know that the area of the reactngle is given by the formula,

A = length × width

here, A = 115.5 in.² and width = 8  in.

115.5 = length × 8

length = 115.5 / 8

length = 14.44 in.

So, XY = WZ =  14.44 in.

For right triangle XYZ using Pythagoras theorem,

XZ² = XY² + YZ²

XZ² = 14.44² + 8²

XZ² = XY² + YZ²

XZ² = 272.51

XZ = 16.51 in.

So, the perimeter of triangle XYZ would be,

P = XY + YZ + XZ

P = 14.44 + 8 + 16.51

P = 38.95 inches
