Answer 1

Answer:

for figure 1

AB= 70.98

BC =40.98

Step-by-step explanation:

for figure 1,

AB/BD =tan45= 1

or, AB =BD= BC+30

AB/BC= tan60 = √3

or, (BC+30)/BC = 1.732 (see above)

or, 30/BC = √3 –1

or, BC = 30/0.732

or, BC = 40.98

AB = 40.98 +30= 70.98

use this method for figure 2 as your exercise.
