A 45-45-90 triangle has a leg of length 5.38. What is the length of the other leg?

Answers

Answer:

5.38 units

Step-by-step explanation:

Because of the base angle theorem converse, This triangle is an isosceles triangle.

Because this is an isosceles triangle, because the leg of the triangle is 5.38 units, that means the other leg has to be 5.38 units

You may be asking, how do I know it's the other leg that's congruent.

Well, the angle opposite to the 90° angle is the hypotenuse, and we want the line segment opposite of the 45° angle. And both the legs are opposite to the 45° angles.

A computer monitor is 23 inches which is the diagonal distance across the screen.If the screen measures 13 inches in height,what is the actual width of the screen to the nearest inch?

Answers

Answer:

width = 19 inches

Step-by-step explanation:

Pythagorean theorem

23^2 = 13^2+x^2

529 = 169+x^2

x^2 = 360

x = 18.97

The actual width of the screen to the nearest inches will be 18.97 inches.

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

A PC screen is 23 inches which is the slanting distance across the screen.

If the screen measures 13 inches in height. Then the actual width of the screen will be given as,

23² = 13² + B²

529 = 169 + B²

B² = 360

B = √360

B = 18.97 inches

The actual width of the screen to the nearest inches will be 18.97 inches.

The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft

Answers

Answer:

b

Step-by-step explanation:

The maximum length of the beluga whale is 17 feet.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The basking shark can grow to a length of 30 feet.

This is 176.47% of the maximum length of the beluga whale.

Assuming the maximum length of a beluga whale is x feet.

So,  176.47% of x is 30 feet.

∴ (176.47/100)×x = 30.

1.7647x = 30.

x = (30/1.7647).

x = 17 feet.
