Never,because obtuse angle is an angle measuring between 90 and 180
and if an angle measures 180 then it is a straight angle

Answer:

Never                                  

Step-by-step explanation:

Definition of Obtuse angle :

An angle whose measure is greater than 90 degree and less than 180 degree.

In other words, Obtuse angle is lies between 90 degree to 180 degree.

Here note that, it is not equal to 90 degree and 180 degree.

Because if angle = 90 degree it is "Right angle'

If angle = 180 degree it is 'Straight Angle'

So, Obtuse angle measure never 180 degree.

How does this polynomial identity work on numerical relationships?<br> (y + x) (ax + b)
Serggg [28]

Let us take 'a' in the place of 'y' so the equation becomes

(y+x) (ax+b)

Step-by-step explanation:

<u>Step 1:</u>

(a + x) (ax + b)

<u>Step 2: Proof</u>

Checking polynomial identity.

(ax+b )(x+a) = FOIL

(ax+b)(x+a)

ax^2+a^2x is the First Term in the FOIL

ax^2 + a^2x + bx + ab

(ax+b)(x+a)+bx+ab is the Second Term in the FOIL

Add both expressions together from First and Second Term  

= ax^2 + a^2x + bx + ab

<u>Step 3: Proof </u>

(ax+b)(x+a) = ax^2 + a^2x + bx + ab

Identity is Found .

Trying with numbers now

(ax+b)(x+a) = ax^2 + a^2x + bx + ab

((2*5)+8)(5+2) =(2*5^2)+(2^2*5)+(8*5)+(2*8)

((10)+8)(7) =(2*25)+(4*5)+(40)+(16)

(18)(7) =(50)+(20)+(56)

126 =126

The temperature outside was 60 degrees when Sarah woke up. By noon, it had increased to 75 degrees. Find the percent increase in
DochEvi [55]
Temp1 = 60
Temp2 = 75
Temp2 - Temp1 = 15

Difference = (Temp2 - Temp1) / Temp1
Difference = 15 / 60 = 1 / 4 = 0.25
Percentage difference = difference * 100% = 0.25 * 100% = 25%

Explain how you can use the inscribed angle theorem to justify its second corollary, that an angle inscribed in a semicircle is
mihalych1998 [28]

Answer:

We find half the measure of the central angle of the circle. Where the given shape is a semi-circle, then the inscribed angle is half of 180, therefore, 90 degrees and a right angle is proven. We show this as Angle BAC is a RA 360 is the measure of circle 360/2 = 180 the semi circle Angle BAC is 180/2 = 90 degree.

Step-by-step explanation:

Hope it helps you!
