hello : <span>
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
</span>
if: Δ = 0 : : x1 =x2 = -b/2a </span> (has a repeated solution)
P=69 degrees
Q=71 degrees
R=40 degrees
Explanation
All triangles equal up to 180 degrees.
First add all numbers without x.
Then add all xs.
5x+20=180
Subtract 20 from 180
5x=160
Divide 160 by 5
x=40
