Find the Error A student states that the exterior angle of a triangle can never be a right angle. Choose the response that ident

ifies the mistake
and corrects it.
O A) There is no mistake. The statement is correct.
OB) An exterior angle of a triangle can be supplementary to the right angle of a right triangle, so an exterior angle can be a right angle.
OC) An exterior angle of a triangle can be complimentary to an acute angle of a right triangle, so an exterior angle can be a right angle.
OD) An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.

Student is wrong  An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.

<h3>What is exterior angle?</h3>

The Exterior Angle is the angle between any side of a shape, and a line extended from the next side.

The student make an error he states that the exterior angle of a triangle can never be a right angle.

The correct answer will be option D that is An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.I have also attached the diagram of the triangle for better understanding.

To know more about exterior angle follow

This is super hard i needd help

Answer:

2587mm^3 approx!

Step-by-step explanation:

first you divide the nut into 6 part(in triangle now, by joining centre to each edge)

let's take one part of the triangular shape then area of that part can be found by using 1/2×base×height

i.e, 1/2×13×15=97.5(mm^2)

now when we consider depth of that traingular part,we will get volume of that part as area×depth

i.e, 97.5×6=585(mm^3)

now volume of all the 6 triangular part is 585×6=3510(in mm^3)

now take circular cavity in consideration, it's volume will be π(7^2)6=923(mm^3) approximately

now reqired volume will be volume of that hexagonal part minus that of circular cavity

=3510-923

=2587mm^3

Arte-miy333 [17]

Answer: 505

Step-by-step explanation:

The formula to find the sample size n , if the prior estimate of the population proportion (p) is known:

n= p(1-p)(\dfrac{z}{E})^2 , where E=  margin of error and z = Critical z-value.

Let p be the population proportion of crashes.

Prior sample size = 250

No. of people experience computer crashes = 75

Prior proportion  of crashes p=\dfrac{75}{250}=0.3

E= 0.04

From z-table , the z-value corresponding to 95% confidence interval = z=1.96

Required sample size will be :

n=0.3(1-0.3)(\dfrac{1.96}{0.04})^2 (Substitute all the values in the above formula)

n= (0.21)(49)^2= 0.21\times2401

n= 504.21\approx505   (Rounded to the next integer.)

∴ Required sample size = 505
