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°

1:

cos (37)= 11/x

x(cos(37))= 11

x= 11/cos(37)

<em>x= 14.4</em>

2:

tan (0)= 4/13

0= tan^-1/ 4/13

0= 0.3

<em>x= 0.3</em>
