Answer:
△PQR and △RST are not similar.
Step-by-step explanation:
In triangle △PQR, two known interior angles are 34° and 80°. So the measure of third angle is
In triangle △RST, two known interior angles are 24° and 90°.
Two triangles are similar if their corresponding angles are same and the corresponding sides are proportional.
Since the angles of △PQR and △RST are not same, therefore we can say that the △PQR and △RST are not similar.
39x-7
The perimeter is all the sides added together so
9x + 8x - 2 + 5x + 1 + 17x - 6
Since you can't solve it you just want to simplify the equation, add the like terms together
9x+8x+5x+17x = 39x
-2+1-6 = -7
Your equation is 39x-7
