Answer:

x = 78°

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°.

x + a + b = 180°

x = 180° -a -b . . . . . . . . add -a-b to both sides

x = 180° -54° -48°

x = 78°

What is the amplitude of the cosine function corresponding to the secant function graphed below ? a. -2 b. -1 c. 2 d. 3

Bas_tet [7]

Answer:

Step-by-step explanation:

From the graph, we obtain the trigonometric function as:

$y=2 \sec x+1$

The corresponding cosine function have equation.

$y=2\cos x+ 1$

This function is of the form: $y=a\cos bx+c$

where $|a|$ is the amplitude.

Therefore the amplitude is |2|=2
