The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that

$7x + 2x+27 = 180$

Sum like terms:

$9x+27 = 180$

Subtract 27 from both sides:

$9x = 153$

Divide both sides by 9:

$x = \dfrac{153}{9} = 17$

What is the slant height of a regular pyramid if its lateral area is 160 units² and the perimeter of the base is 40 units?

SSSSS [86.1K]

Answer:

The slant height of a regular pyramid is $l=8\ units$

Step-by-step explanation:

we know that

The lateral area of a regular pyramid is equal to

$LA=\frac{1}{2}Pl$

where

LA is the lateral area

P is the perimeter of the base

l is the slant height

we have

$LA=160\ units^{2}$

$P=40\ units$

substitute in the formula and solve for l

$160=\frac{1}{2}(40)l$

$160=20l$

$l=160/20$

$l=8\ units$
