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.
Answer: -2a,-2b
Step-by-step explanation:
Answer:
Answer: =2a + 16
Step-by-step explanation:
8+9−1+2a =8+9+−1+2a
now its time to to do CLT
=8+9+−1+2a
=(2a)+(8+9+−1)
=2a+16
Let's solve it!
So, let's study each factor.
x + 7 = 0 -> x = -7
x² - 49 = 0 -> x² = 49 - > x = ± √49 -> x = <span>± 7
Final answer: x = 7 and x = -7
