Answer:
A, D, E
Step-by-step explanation:
The ratio height : base is ...
... 2.5 : 1.6
... = 25 : 16
... = 1.5625 : 1
You can eliminate the bogus answers B and C because ...
... B: the numbers are too close together. The larger would need to be near 13 for the smaller one to be 9.

Answer:
(x+3)( 5x-3)
Step-by-step explanation:
f(x) = 5x² + 12x – 9
Factor
(x+3)( 5x-3)
Let one angle be x.
Other angle = x + 30°
Given, angles are complementary;
x + x + 30 = 90
2x = 60
x = 30°
Hence, the angles are 30° and 60°.
