Answer:
Well, if we know that an obtuse angle is an angle greater than 90 degrees, and that a triangle's angles MUST sum up to 180 degrees and contain three angles. Then it logically follows that there's no way for a triangle to have 3 angles AND have two of the three be greater than or equal to 90 degrees as the remaining angle would have to be zero degrees or some "negative angle"- which I am pretty sure doesn't exist lol! As for a proof, I think you can cook up something with what I have given you so far :)
<span>triangle abc is similar to triangle def
</span>
m<b = m<e = 25
so
m<d = m<a = 45
answer:
<span>measure of angle a= 45 degrees</span>
[Ne] 3s^2 3p^2. is the correct answer :)
Answer: number 2
Step-by-step explanation: so a supplementary Angle adds up to a 180 angle so it would be number 2 I think.
Answer:
y = x + 5
Step-by-step explanation:
The line passes through points (-7,-2) and (2,7)
Slope of the line = change in y ÷ change in x =
= 1
Taking another point (x,y) on the line;
Slope =
= 1
Cross multiplying this gives;
y - 7 = x - 2
y = x + 5
