what the angle of the triangle are in the ration

Answers

Answer 1

Answer:

Since the ratio of the angles is 7:2:1, we can write the angles as 7x, 2x, and x, for some x. Since the sum of the angles in a triangles is 180, we have 7x + 2x + x = 180. Combining the x's on the left-hand side, we have 10x = 180. Finally, dividing by 10 gives x = 18.

In ΔXYZ, z = 75 inches, x = 26 inches and ∠Y=135°. Find the length of y, to the nearest inch.

The length of the y of the triangle is y = 96 inches

What is Law of Cosines?

The Law of Cosines is a mathematical formula used to find an unknown side or angle of a triangle, given the lengths of the other two sides and the angle opposite the unknown side. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite side c, the following equation is true:

c² = a² + b² - 2ab cos(C)

where cos(C) is the cosine of angle C. This formula can be rearranged to solve for any of the variables, depending on which values are known.

Given data ,

Let the triangle be represented as ΔXYZ

And , the measures of the sides of the triangle are

z = 75 inches

x = 26 inches

And , the measure of ∠Y = 135°

We can use the Law of Cosines to find the length of y, since we know two sides and the included angle of the triangle.

The Law of Cosines states that:

c² = a² + b² - 2ab cos(C)

where c is the side opposite angle C, and a and b are the other two sides.

In this case, we want to find the length of side y, which is opposite angle Y. So we can write:

y² = x² + z² - 2xz cos(Y)

Substituting in the given values, we get:

y² = 26² + 75² + 2(26)(75) cos(135°)

Simplifying, we get:

y² = 676 + 5625 - 2925√2

y² ≈ 9163

Taking the square root of both sides, we get:

y ≈ 95.76

Rounding to the nearest inch, we get:

y ≈ 96 inches

Hence , the length of y, to the nearest inch, is 96 inches

what does this mean 4x + 6y=9

Answers

Answer: Infinite solutions

Step-by-step explanation:

Solve4x+6y=9for x:

4x+6y=9

4x+6y+−6y=9+−6y(Add -6y to both sides)

4x=−6y+9

4x /4 = −6y+9 /4

(Divide both sides by 4)

x= −3 /2 y+ 9 /4

Substitute

−3 /2 y+ 9 /4

for x in 12x+18y=27:

12x+18y=27

12( −3 /2 y+ 9 /4 )+18y=27

27=27(Simplify both sides of the equation)

27+−27=27+−27(Add -27 to both sides)

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker

Answers

By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.

What is the vοlume οf a cylinder ?

The fοrmula tο calculate the vοlume οf a cylinder:

V = πr²h

where:

V = vοlume

r = radius

h = height

Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.

In this case, we have:

r = 9 mm

h = 32 mm

Sο the fοrmula becοmes:

V = π(9 mm)²(32 mm)

V = π(81 mm²)(32 mm)

V = 81π(32) mm³

V ≈ 8,159.15 mm³

Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

where

B denotes the area of the base

and h denotes the height of the prism.

Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)

by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.

Now just simplify the right side to get -25 + 11 or -14.

So f(-5) = -14.
