Answer:

Step-by-step explanation:

I think this means you want the secant between 0 and 90 degrees.

The Secant(theta) = 1/Cos(theta)

Cos(theta) = 2/3

1/cos(theta) = 1//2/3 = 3/2

Answer: C

Instructions: Find the lengths of the other two sides of the isosceles right triangle below.

Alexandra [31]

Given:

The ratio of 45-45-90 triangle is $x:x:x\sqrt{2}$ .

The hypotenuse of the given isosceles right triangle is $7\sqrt{2}$ .

To find:

The lengths of the other two sides of the given isosceles right triangle.

Solution:

Let $l$ be the lengths of the other two sides of the given isosceles right triangle.

From the given information if is clear that he ratio of equal side and hypotenuse is $x:x\sqrt{2}$ . So,

$\dfrac{x}{x\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{1}{\sqrt{2}}=\dfrac{l}{7\sqrt{2}}$

$\dfrac{7\sqrt{2}}{\sqrt{2}}=l$

$7=l$

Therefore, the lengths of the other two sides of the given isosceles right triangle are 7 units.

Yossi used to have a square garage with 334ft^2 of floor space. He recently built an addition to it. The garage is still square,

vaieri [72.5K]

Answer:

Increase in the length of one side = 3.8 ft

Step-by-step explanation:

Yossi has garage whose area is 280 ft²

After rebuilt their is increment in area by 50%

New Area = 280 × 150% = 420 ft²

Also we know that Area of Square = (Length) × (Length)

⇒ Length of Newly built garage = √420 = 20.5 ft

and Length of Originally garage = √280 = 16.7 ft

⇒ Increase in the length of one side = 20.5 - 16.7 = 3.8 ft
