Question

Find the length of AB​

Answer 1

Step-by-step explanation:

from triangle APQ

$= > tan \: 30 = \frac{10}{AP} \\ \\ = > \frac{1}{ \sqrt{3} } = \frac{10}{AP} \\ \\ = > AP = 10 \sqrt{3} \: cm$

from triangle PBR

$= > tan \: 45 = \frac{PB}{8} \\ \\ = > 1 = \frac{PB}{8} \\ \\ = > PB = 8 \: cm$

therefore

=AB

= AP+PB

= 10√3 + 8

= 10x1.73 + 8

= 17.3 + 8

= 25.3 cm

Answer 2

Answer:

18 cm is the length of AB
