Answer:
(-7a-15)/3
Step-by-step explanation:
- 7 = 3/a ( x + 5)
open the bracket
-7 =3/a(x)+ 3/a(5)
-7 = 3x/a+ 15/a
l.c.m is a
-7= 3x+15/a
cross multiply
-7a = 3x+15
-7a-15 = 3x
(-7a-15)/3 = x
18/10
M= 9/5
Hope this helps

Let a chord join YZ, then angle XYZ = 90° and angle XZY = 90 - 54 = 36°
angle OYZ = angle XZY = 36°
Therefore, the measure of YZ = 180 - 36 - 36 = 108°
