9514 1404 393

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°

Bas_tet [7]

Answer:

2

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
