Answer:
The Answer is yes to both of your questions.
Step-by-step explanation:
SSS (Side angle Side) = Because If 3 sides of triangle are congruent to 3 sides of another triangle, the triangles are congruent. SAS (Side angle side) = If 2 sides and the angle in between are congruent to the corresponding parts of another triangle, the triangles are congruent.
Answer:
130° is the correct answer
∠QPR=80°
∠PQR+∠QPR+∠QRP=180°
∠PQR+∠QRP=100°
2(x+y)=100°
x+y=50°
So, in △QOR
x+y+∠QOR=180°
∴∠QOR=180°−50°
=130°
<span>D = 4 - 4*9*(-7) = 4 + 252 = 256 = 16*16
x1 = (-2 + 16)/9 = 14/ 9
x2 = (-2 - 16) / 9 = -2

Answer:
x=5+√136or x=5−√136
Step-by-step explanation:
To solve this equation we have to factorize 3x2−5x+1. Since we can not use any
-3(4x-1) = C. -12x + 3
