-2/3 is the slope of 3y + 2x = 1
Answer:
Step-by-step explanation:
for missing angle of triangle ABC
let the missing angle be y
31+111+x=180(sum of interior angle of a triangle is 180 degree)
142+y=180
y=180-142
y=38 degree
x=y(being alternate angles)
x=38 degree
Answer:
Option D is correct.
Step-by-step explanation:
We have been given 
We need to tell which one of them will give the perfect square trinomial.
Trinomial is the polynomial with three terms.

If we factorize it by middle term splitting we get:



is the perfect square trinomial.
Therefore, option D is correct
