find the value of A, B
Answers
Answer:
Required Answer:-
GiveN:
A triangle PMN whose two of the exterior angles are x and y.
x > y
To Prove:
MP > NP
Step-by-step Explanation:
We have,
• x > y
Multiplying -1 both sides, and Remember! Whenever we multiply or divide an inequality by a negative number, you must flip the inequality sign.
➛ -x < -y
Now add 180° both sides,
➛ 180° - x < 180° - y
And in the figure, we can see that ∠PMN = 180° - x and ∠PNM = 180° - y. Hence,
➛ ∠PMN < ∠PNM
We know, The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle. ∠PMN is opposite to NP and ∠PNM is opposite to MP..
Thus:-
➛ PN < PM
Hence proved!!

and
b
=

8
Explanation:
This appears to be a way of finding a number
a
, which when added to
x
