You can write this (2p-11)^2=0
So answer is 11/2
Answer:
25x^2-40x+16
Step-by-step explanation:
(5x-4)(5x-4)
= 25x^2-20x-20x+16
=25x^2-40x+16
That can be written as a complex number:-
= -108 - √3 i
1. The sum of of the interior angles of a triangle is 180°.
2. Keeping this on mind, you have:
A+B+C=180
<span>
A=11x-4
B = 4x-11
C=63-4x
</span>
3. When you substitute these values, you obtain:
A+B+C=180
11x-4+4x-11+63-4x=180
11x+48=180
11x=180-48
11x=132
x=132/11
x=12
3. Therefore:
A=11(12)-4
A=128°
B = 4(12)-11
B=37°
C=63-4(12)
C=15°
5. The answer is:
A. AB, AC, BC
