X = 89

A triangle always equals 180°. Because two out of three angles are given, the two known angles (42° and 49°) can be added together which is 91°. The 91° can be subtracted from 180° to find the unknown angle x.

Required

Identify a and b

The given equation is an exponential function and the general form is:

$f(x) = ab^x$

When $f(x) = ab^x$ is compared to $f(x) = 3(\frac{1}{5})^x$

We have that: $a = 3$ and $b = \frac{1}{5}$
