Find the slant height x of the pyramid shown, to the nearest tenth.<br> 5 mm<br> 9 mm<br> 9 mm
MArishka [77]

The slant height of the pyramid can be calculated using Pythagoras theorem. Therefore, the slant height is 6.7 mm

<h3>How to find slant height of a pyramid?</h3>

The slant height x, can be found using Pythagoras theorem,

Therefore,

c² = a² + b²

where

  • c = hypotenuse
  • a and b are other two legs.

Therefore,

x² = 4.5² + 5²

x² = 20.25 + 25

x² = 45.25

x = √45.25

x = 6.72681202354

x = 6.7 mm

What is the value of Z?
sukhopar [10]

Answer:

Step-by-step explanation:

Both x and y are inscribed angles.  The value of an inscribed angle is half the measure of its intercepted arc.  This means that x has a value of 33°, and y has a value of 48°.  That means that, according to the triangle angle sum theorem, the third angle has to equal 180 - 33 - 48 = 99°.

This angle is vertical with angle z, so angle z also equals 99°
