Answer:
x = 27
Step-by-step explanation:
(whole secant) * (external part) = (tangent)^2
(x+48)* 48 = 60^2
(x+48)* 48 = 3600
Divide each side by 48
x+48 =75
Subtract 48 from each side
x = 75-48
x=27
Answer:
Equations would be;
<u>30 + 50 + y = 180 </u>
and
<u>y = 180 - 80</u>
Additional:
If you are looking for y and u value then here they are:
y = 100°
u = 25°
Hope this helps!
25 is your answer. 4X4+9= 25
