Answer:Its 5*4, 4*3, and 6*4
Step-by-step explanation:
Answer:
The answer is 148 degrees
Step-by-step explanation:
I'm pretty sure it is 148°... In my notes it says "if a tangent to a circle & a chord intersect at a point on the circle, then the measure of each angle they form is one-half the measure of its intercepted arc." Hope this helps...

See the attached figure to better understand the problem
we know that
in the triangle BCD
y²+5.66²=z²-------> y²=z²-5.66²------> equation 1
in the triangle ABC
y²+5.66²=x²-------> y²=x²-5.66²------> equation 2
equals 1 and 2
z²-5.66²=x²-5.66²--------> z²=x²---------> z=x
if z=x then
angle A=45°
angle D=45°
in the triangle ABD
cos 45=z/(5.66*2)-------> z=11.32*cos 45-----> 11.32*√2/2----> 8
z=8
x=8
y²=z²-5.66²------> 8²-5.66²-----> y²=31.96------> y=5.65
the answer isthe value of x is 8the value of z is 8the value of y=5.65
Answer:
![\phi=\theta a2](https://tex.z-dn.net/?f=%5Cphi%3D%5Ctheta%20a2)
Step-by-step explanation:

we know that
In the figure ABCD
![m](https://tex.z-dn.net/?f=m%3CADC%3D%5Ctheta%20a1)
![m](https://tex.z-dn.net/?f=m%3CDAB%3D90%5C%C2%B0)
![m](https://tex.z-dn.net/?f=m%3CABC%3D90%5C%C2%B0)
![m](https://tex.z-dn.net/?f=m%3CDCB%3D90%5C%C2%B0%2B%5Cphi)
Remember that the sum of the internal angles in a quadrilateral is equal to ![360\°](https://tex.z-dn.net/?f=360%5C%C2%B0)
so
![\theta a1+90\°+90\°+90\°+\phi=360\°](https://tex.z-dn.net/?f=%5Ctheta%20a1%2B90%5C%C2%B0%2B90%5C%C2%B0%2B90%5C%C2%B0%2B%5Cphi%3D360%5C%C2%B0)
-----> complementary angles
and
-------> complementary angles too
so
![\phi=\theta a2](https://tex.z-dn.net/?f=%5Cphi%3D%5Ctheta%20a2)
