Question

PLEASE HELP ASAP! 100 PTS *TRIGONOMETRY*

Answer 1

Step-by-step explanation:

solution:

A.

relation between hypotenuse and base is given by cos angle

so

$\cos(ø)$=base/hypotenuse=11/x

cos37°=11/x

x=11/(cos37°)=13.77units

side indicated =x=13.77units

solution:

B.

relation between perpendicular and base is given by tan angle

so

$\tan(ø)$=perpendicular/base=4/13

ø=tan-¹ (4/13)=17.10°

angle indicated =ø=17.10°

Answer 2

1:

cos (37)= 11/x

x(cos(37))= 11

x= 11/cos(37)

x= 14.4

2:

tan (0)= 4/13

0= tan^-1/ 4/13

0= 0.3

x= 0.3

have a nice day :)
