Answer:

√122

Step-by-step explanation:

Find the length of the third side. If necessary, write in simplest radical form. square root of 58 8

let the given sides be;

Hypotenuse = x

Adjacent = √58

Opposite = 8

Using pythagoras theorem;

hyp^2 = opp^2 + adj^2

x^2 = (√58)^2+8^2

x^2 = 58 + 64

x^2 = 122

x = √122

Hence the length of the unknown side is √122

Answer:

Step-by-step explanation:

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

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

Answer:

19.2 oz

Step-by-step explanation:

Hi! so for the problem you are trying to find out the percentage. To find the percentage of any number you multiply the whole number (in this case 32 oz) by the percent in decimal form (in this case 60% is 0.60). So... 32oz x 0.60 is 19.2 oz. Hope this helped!

Answer:

The last container needs one more slice to be filled up.

Step-by-step explanation:

From the question, we know that only 3 oranges can fit into a container.

However, the company has 26 oranges that need to be inside containers.

We can find out the number of containers that will be filled up completely and the remainder left.

We will do this by dividing the number of orange slices available by the number that can fit into a container.

This is 26 / 3 = 8 remainder 2

Therefore, 8 containers will be filled up, with only two oranges left in the last container.

Remember that each container needs up to 3 oranges to be filled up. Since the last container has only 2 orange slices in it, it needs one more slice to be filled up.

Answer:

Step-by-step explanation:

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.

52+x=90

x=38

Answer:

x=38 degrees

Step-by-step explanation:

You know that x degree angle plus 52 degree angle have to equal 90 degrees. Therefore, the equation is x+52=90. You want to isolate x so you have to subtract 52 from both sides. The equation will look like x=90-52. Simplify this to get x=38. Therefore, x= 38 degrees.
