Answer:
1. x^2+12x+32
Step-by-step explanation:
(x+8)(x+4)
x(x+4)+8(x+4)
x^2+4x+8x+32
x^2+12x+32
Given:
A quadrilateral inscribed in a circle.
To find:
The value of x and y.
Solution:
If a quadrilateral inscribed in a circle, then it is known as cyclic quadrilateral and the opposite angles of a cyclic quadrilateral are supplementary angles, it means their sum is 180 degrees.
[Supplementary angles]



The value of x is 14 degrees.
[Supplementary angles]



Therefore, the value of x is 14 degrees and the value of y is 38 degrees.
Answer:
Step-by-step explanation:
Their is no answer sorry
Multiplying both sides by cos x and dividing both sides by tan x results in
<span>cos x = (sin x)/(tan x), and sticking in the numbers gives </span>
<span>cos x = 0.99/7.07 = 0.14.</span>
