14.

y = 75, its a vertical angle to 75.

x = 75, its a vertical angle to 75, or alternate interior angle to 75.

15.

y = 74, its a supplementary angle with 106.

x = 106, its a corresponding angle to 106.

16.

y = 90, its a supplementary angle with x.

x = 90, its a corresponding angle with 90.

There are two triangles in the figure(triangular prism) option third is correct.

<h3>What is a triangular prism?</h3>

When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is a name given to this novel 3D object.

The complete question is:

How many triangles are needed to draw the net of this object?

For the figure please refer to the attached picture.

As we can see in the figure we have given a triangular prism:

The triangular prism has two triangles.

A triangle for the base of the prism and a triangle for the top of the prism.

The lateral faces of the prism are rectangular.

Thus, there are two triangles in the figure(triangular prism) option third is correct.

Forensic scientists use the following law to determine the time of death of accident or murder victims. If T denotes the tempera

Naddik [55]

Answer: He was killed 24.83 hours before the body was found.

Step-by-step explanation:

Since we have given that

$T=T_0+(T_1-T_0)(0.97)^t$

Here, T is the temperature of a body t hr after death, T = 82°F

T₀ is the air temperature , T₀ = 67°F

T₁ is the body temperature at the time of death = T₁ = 98.6°F

So, we will substitute all the values in the above equation.

$82=67+(98.6-67)(0.97)^t\\\\82-67=31.6(0.97)^t\\\\\dfrac{15}{31.6}=(0.97)^t\\\\0.474683544=(0.97)^t\\\\\text{Taking ln on both sides}\\\\\ln(0.474683544)=t\ln(0.97)\\\\-0.745=t\times -0.030\\\\t=\dfrac{0.745}{0.030}\\\\t=24.83\ hours$

Hence, he was killed 24.83 hours before the body was found.
