Mathematics
1 answer:
Neko [114]3 years ago
7 0

Answer:

ED=32\ units

Step-by-step explanation:

we know that

Applying the Intersecting Secant Theorem

AC*BC=EC*DC

substitute the values

(16+5)*(5)=(ED+3)*(3)

Solve for ED

(21)*(5)=(ED+3)*(3)

35=(ED+3)

ED=35-3=32\ units

Use the formula M = NPQ to solve for the following variables.
Oksanka [162]

Step-by-step explanation:

M=NPQ

m/pq=Npq/pq

pq is going to cancel, you left with N

N= m/pq

To solve for q, we have to make q the subject.

m = Npq

divide both sides of the equation by NP

M/NP= q

that's the answer

Find the value of X. I can't figure out what to do when one is at a right angle.
AnnyKZ [126]

Answer:

x = 20

Step-by-step explanation:

Two lines are parallel. So, alternate interior angles are congruent.

x +8 + 6x - 58 = 90

7x - 50 = 90

        7x = 90 +50

       7x = 140

         x = 140/7

x = 20
