When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 6x + 19 = 180
7x + 19 = 180
7x = 161
x = 23
Now solve for B.
6(23) + 19 = B
138 + 19 = B
157 = B
The measure of angle B is 157 degrees
Hope this helps =)
Answer:
23.3 cm
Step-by-step explanation:
use Pythagoras Theorem
length BD= 16²+10²= 356
√356= 18.9 cm
length DH= 30²-18.9²= 542.8
√542.8= 23.3 cm
DH=AE
Hence, AE= 23.3 cm
