Answer:

z = 30; obtuse isosceles triangle

Step-by-step explanation:

4z + z + 30 = 180

5z + 30 = 180

5z (+ 30 - 30) = 180 - 30

5z = 150

5z/5 = 150/5

z = 30

Since z = 30, and 30 = 30, two angles are congruent to each other and there is only one obtuse angle. Therefore, this is an obtuse isosceles triangle.

Write the expression of polynomial a given the roots:
Liono4ka [1.6K]

Answer:

So it looks like the given zeros are 2i and -3. We have to work backwards.

x = -3 and x = 2i

For -3, we know that out factored form before would have been x + 3

For 2i, that means we took the square root of negative number because it is imaginary. So that means out factored for x2 + 4

So if we put these together:

(x2 + 4)(x + 3) = x3 + 3x2 + 4x + 12

The surface area of this triangular pyramid, whose base and lateral faces are congruent equilateral triangles, is __ square inch
DedPeter [7]

Answer:

The surface area is equal to 390\ in^{2}

Step-by-step explanation:

The surface area of the triangular pyramid is equal to the area of its four triangular faces

so

In this problem

SA=4[\frac{1}{2}(b)(h)]

we have

b=15\ in

h=13\ in

substitute the values

SA=4[\frac{1}{2}(15)(13)]=390\ in^{2}
