Mathematics
1 answer:
Vikentia [17]3 years ago
6 0

Answer:

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

Step-by-step explanation:

x=  −b±√b2−4ac /2a

x= −(1)±√(1)2−4(−2)(8) /2(−2)

x= −1±√65 /−4

x= 1/4 +(-1/4) √65 or x= 1/4 + 1/4 √65

In each triangle p is the circumcenter use circumcenter theorem to solve for the givin values
timurjin [86]

Answer:

Circumcenter theorem states that the vertices of the each triangle are equidistant from the circumcenter.

As per the statement:

It is given that: P is the circumference

From the given figure:

CP = 12 units.

then;

by circumcenter theorem;

AP= BP =CP = 12 units.

Next find the value of AB:

Labelled the diagram:

AD = 11 units

then;

AB = AD+DB

Since: AD=DB [You can see it from the given figure]

then;

AB = 2AD = 2(11) = 22 units

Therefore, the value of BP and AB are: 12 units and 22 units
