Step-by-step explanation:
<h2>These measurements will not form a triangle.</h2>
Step-by-step explanation:
We have sine formula

Given
a = 9.7
b = 49
A = 26°
Substituting

Value of sin B is greater than 1, which is not possible.
Hence these measurements will not form a triangle.
18 / 1 = x / 15......18 miles to 1 gallon = x miles to 15 gallon
cross multiply
(1)(x) = (18)(15)
x = 270 miles
