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

Apply the Pythagorean Theorem to find the distance between points B and C. A) 18 units B) 55 units C) 64 units D) 73 units

nadya68 [22]

Answer:

$BC=\sqrt{73}$

Step-by-step explanation:

Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.

If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.

If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.

Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

$BC=hyp=\sqrt{8^2+3^2} =\sqrt{64+9} =\sqrt{73}$

A square pyramid is shown. What is the surface area?

ICE Princess25 [194]

Answer:The answer is B

Step-by-step explanation:

first find te height:

1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)

now do the pythagorean theorem:

a^2+0.75^2=3^2

(height)= 2.905

A= a^2+2a√((a^2/4)+h^2)

a (base edge)= 1.5

h (height)= 2.905

Calculate and you get B as your answer.

Hope this elpsand you get this right!
