If Angle "a" is 25o, Angle "b" is: equal to 25 o greater than 25 o less than 25 o

jhonyy9:

like a first step do you know the sum of angle measures of a triangle equal how many ?

jhonyy9:

and this 25 o wan be 25°

jhonyy9:

@supie any idea ?

supie:

Actually, no.

Divaseventeen:

The f####n.people just gave me this d##n picture

Divaseventeen:

Sorry I dont like this question.

jhonyy9:

so we start we this what i ve asked that the sum of angle measures of a triangle equal 180 degrees yes ? and now than we know that angle a has 25 degrees so this mean that the other 2 angles has in case of isosceles triangle together 180-25 = 155 degrees what divided by 2 you get 77,5 degrees

jhonyy9:

@supie what about this ?

jhonyy9:

@Laylalyssa

jhonyy9:

so in this case i think the measure of angle b depend the measure of angle c

Laylalyssa:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Divaseventeen The f####n.people just gave me this d##n picture \(\color{#0cbb34}{\text{End of Quote}}\) ?theres a picture?

jhonyy9:

no - this is in general considered

Divaseventeen:

Do you want the picture

Laylalyssa:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Divaseventeen Do you want the picture \(\color{#0cbb34}{\text{End of Quote}}\) yes

jhonyy9:

@Divaseventeen why ? there exist a picture about this ?

mxddi3:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @jhonyy9 so in this case i think the measure of angle b depend the measure of angle c \(\color{#0cbb34}{\text{End of Quote}}\) yes, i think if there is an image then we will be able to decide because we can't really say the measure of angle b unless we know angle C. Unless they are equal then we would do as jhonny said 155/2=77.5

Divaseventeen:

They gave me a picture but it does not help

jhonyy9:

yes @mxddi3 but remember there exist a rule for length of sides too that the length of a side not can be greater than the sum of the other two - or something in this way - so i think that in case of angles is the same

mxddi3:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Divaseventeen They gave me a picture but it does not help \(\color{#0cbb34}{\text{End of Quote}}\) can we please see the image?

jhonyy9:

|dw:1609354144064:dw|

jhonyy9:

any ideas now ?

jhonyy9:

can be the measure of angle B smaller than the measure of angle A ?

Divaseventeen:

Oh we dont have the same picture

Laylalyssa:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @Divaseventeen Oh we dont have the same picture \(\color{#0cbb34}{\text{End of Quote}}\) send the picture then

Divaseventeen:

I think i figured it out thanks to all of you guys

Divaseventeen:

Especially jhonyy9
