<1 = 123
60 + 63 = 123
180 - 123 = 57
180 n- 57 = 123
Triangle angle-sum theorem
Alternate exterior angles theorem (?)
Same side interior angles theorem
idk what the last one is about sorry
hope this helps
A triangle, it might be an obtuse
Given:
Consider the given function:

To prove:

Solution:
We have,

Substituting
, we get




Substituting
, we get




Substituting
, we get




Using the algebraic formula, we get
![[\because b^2-a^2=(b-a)(b+a)]](https://tex.z-dn.net/?f=%5B%5Cbecause%20b%5E2-a%5E2%3D%28b-a%29%28b%2Ba%29%5D)

[Commutative property of addition]
Now,




Hence proved.
Answer:
the answer is $2,883$
Step-by-step explanation:
You can multiply the fraction by any number you want so the new fraction gonna be equivalent to your fraction like : (4 × 2)/(5 × 2) = 8/10 or (4 × 3) / ( 5×3) = 12/15 so 4/5 = 8/10 = 12/15 :))
i hope this be helpful
