So a square pyramid is like the pyramids in egypt so
surface area of pyhraid=base+4 triangles
surface area=144
baswe=36
subsitute
144=36+4 times triangles
subtract 36 from both sides
108=4 triggles
divide by 4
27=trignels

the area of 1 triangle is 27 ft^2

Form a polynomial whose real zeros and degree are given.

Hitman42 [59]

Answer:

Step-by-step explanation:

Given that zeroes of a polynomial are

-3, -1, 1, 4

Degree of the polynomial is 4

Also leading coefficient is 1.

So we find easily the polynomial

Since polynomial is 0 at the given four points the polynomial is a product of

$(x+3)(x+1)(x-1)(x-4)\\=(x^2-1)(x^2-x-12)\\= (x^4-x^3-13x^2+x+12)$

Since leading coefficient is given to be 1 we need not multiply an arbitrary constant a

so the required polynomial is

$(x^4-x^3-13x^2+x+12)$

An angle measures 23.4° more than the measure of its complementary angle. What is the measure of each angle?

kodGreya [7K]

Answer:

62°

Step-by-step explanation:

Complementary angles by definition are two or more angles that add up to 90°. So we must do 90°-62° to get the missing angle which is 62°.

Hope that helped.
