Answer:
The two triangles may be congruent, but additional information is needed about the sides of each triangle.
Step-by-step explanation:
Given that Samantha measured two of the angles in PQR and found that they had measures of 65° and 70°. Then, she measured two of the angles in XYZ and found that they had measures of 65° and 45°.
We have by using properties of sum of angles of triangles, angles of PQR are 65, 70, 45 and also same for XYZ
Hence there is a chance that these triangles may be congruent depending on the sides. We are sure that the angles are congruent hence triangles are similar. But to prove congruence we must have additional information about sides.
The two triangles may be congruent, but additional information is needed about the sides of each triangle.

Multiply both the numerator (top) and denominator (bottom) by any
number (the same for both), and you'll have a fraction that is
equivalent to the fraction you gave.
For example, multiply both by 2, and you have 6/10, which is equivalent
to 3/5. Multiply both by 8, and you have 24/40, which is also
equivalent to 3/5. </span>
First lets combine terms.
<span>4x 2 + 5x + 2 = 2x 2 + 7x – 1 subtract the left side from right side
</span>
(4x 2- 2x 2) + (5x - 7x) + (2 + 1)=0 then combining
2x 2 - 2x + 3 =0 now we can use the quadratic formula
