Answer 1

Answer:

55 degree bz sum of interior angles of triangle =180 degree = 180-(35+90)= 55

Answer 2

Given, a right angled triangle ACB with angle ACB=90° and angle ABC=35°.

Since the sum of all angles in a triangle is 180°

Let angle BAC=x

90+35+x=180

x=180-125

x=55°

Thus, angle BAC=55°.

cos(BAC) = cos(55°) = 0.8191

Thus,

AC/AB=0.8191

4/AB=0.8191

AB=4/0.8191

AB=4.883

Rounding to the nearest hundredth,

AB=4.88
