Answer:
The measure of angle A = 65°
Step-by-step explanation:
The sum of opposite angles of cyclic quadrilateral is 180°
From the figure we can see that,quadrilateral ABCD is inscribed in a circle.
<u>To find the value of x</u>
m<B + m<D = 180°
x + 148 = 180
x = 180 - 148 = 32°
<u>To find the value of angle A</u>
m<A = 2x + 1
x = 32
m<A = 2*32 + 1 = 64 + 1 = 65°
Therefore the measure of angle A = 65°
Answer:
X 8
Step-by-step explanation:
Using trial and error
x^4+5x^2-36 factors to (x-2)(x+2)(x^2+9)
2x^2+9x-5 factors to (x+5)(2x-1)
so
(x-2)(x+2)(x^2+9)(x+5)(2x-1)=0
set each to zero
x-2=0
x=2
x+2=0
x=-2
x^2+9=0
x^2=-9
x=3√-1
x=3i
x+5=0
x=-5
2x-1=0
2x=1
x=1/2=0.5
roots are
x=-5-2,0.5,2, and the imaginary root 3i
