Answer:
A
Step-by-step explanation:
The triangles aren't similar.
The triangles share a side so we cant use anything involving SSS SAS.
The triangles has only known congruent angle so we cant use AA.
Answer: b
Step-by-step explanation:
10 x 10= 100
15 x 10= 150
100+150= 250
<u>Answer:</u>
are two roots of equation 
<u>Solution:</u>
Need to solve given equation using quadratic formula.

General form of quadratic equation is 
And quadratic formula for getting roots of quadratic equation is

In our case b = -1 , a = -3 and c = -3
Calculating roots of the equation we get

Since
is equal to -35, which is less than zero, so given equation will not have real roots and have complex roots.
