I have to correct math, but I don't know the answer. The problem is:
In a triangle, the two angles Alpha = 25° and Beta = 80°. What is the size of the angle Gamma? Write down your calculation.
Can someone please write me the answer? We can also Google this, but I can't find the solution.

Loading...Heyho, I'm currently in the 10th grade at a secondary school in Hesse. This semester, I've already received two Fs and am currently earning a C or C- in my oral exam. What grade can I expect on my report card?
I hate even "small" crowds and always get so panicky, like I can't breathe and I'm shaking. It's so embarrassing, wtf I can't give presentations in front of the class either. I always talk way too fast because I want to get it over with quickly. My heart beats really fast and loudly, I sweat…

What is the volume of oxygen gas released from 88 g of carbon dioxide by a chemical reaction under standard conditions (101 kPa, 0 °C)? The correct value would be 44.8 g
I wanted to ask if you have done a massage course and what your favorite subject is/was and what you found easiest or what you find easiest?
75 %
Alpha + Beta =105
180-105 = 75
In order to understand the internal sum is always 180°
You have Alpha=25° and Beta =80°
You’re coming to 105 together.
You lack gamma and if the total is 180 ° and you already have 105° must be the remaining 75° gamma.
Thanks Jula97
A triangle has three corners and thus 3 inner angles. The sum of these inner angles is always 180°.
So 180°-25°(alpha) -80°(beta) =75°(gamma)
Then I guess you didn’t even pay attention when the technical terms were called. For example on Youtube look for “lehrerschmidt trieck winkel sum”.

I just wanted to know how to write it down. I am wrongly expressed apology to all
Too difficult…
Do you know the angular sum in the triangle? If no, why not?

Gamma=180°-(25°+80°)=180°-105°=75°
Supermegagood tip: The sum of the inner angles is always 180°
No. Not in the curved room. On Earth’s surface, for example, it’s different. Only in the Euclidean geometry is the sum of 180°.
The sum of the inner angles in the triangle is always 180°.
Now you’re back.
Too difficult
You should learn more if you don’t understand.
I understand, but I didn’t know how to write it down. I have misjudged
