Question

Find m in the diagram please.

Answer 1

Use csc (90) = 10/m.

So, m = 10/csc(90).

m = 8.93997

Answer 2

m = 8

Explanation:

Here's your solution

=> in traingle DHF and traingle EGF

we have angle DHF and EGF = 90°

and angle F is common , so both traingle are similar by AA similarity

=> 12/m = 15/10

=> m = 120/15

=> m = 8

hope it helps and your day will be full of happiness
