Find the slant height of a square pyramid with base edges of 12 cm and an altitude of 8 cm?
liberstina [14]
To find the slant height we must take apart the pyramid first. Let us cut it in half. There we can easily see that the slant height is really just the hypotenuse of the triangle formed by half the base and the altitude.

Half the base length would be 6 cm.

Using the Pythagorean therom:

a² + b² = c²
6² + 8² = c²
36 + 64 = c²
100 = c²
c = 10

The slant height should be 10 cm. Hope this helps!

The sum of two numbers is 51.
Firdavs [7]

Answer:

21 and 30

Step-by-step explanation:

x + y = 51

x - y = 9

add the two equations and y's will cancel out

2x = 42  divide by 2

x = 21   so put 21 in for x in the top equation and solve

21 + y = 51

y = 30

Please help it’s geometry
murzikaleks [220]

Answer:

x = -4

Step-by-step explanation:

EM = 5x

ET is half of EM so this statement is true: 5x = 2(3x + 2)

Solve for x.

5x = 2(3x +2)

Distribute 2.

5x = 6x + 4

Isolate x.

-x = 4

Divide -1 out.

x = -4
