What's the value of x and y?

Answer:
x = 45 and y = 90
Step-by-step explanation:
Let the third angle be z
z = 180 - 135 (Linear Pair)
z = 45
Since its an iscosceles triangle,
<z = <x (angles opposite to equal sides have equal angles)
<x = 45 degree
<z + <x + <y = 180
45 + 45+ <y = 180
90 + <y = 180
<y = 180 - 90
<y = 90
Therefore x = 45 and y = 90

Answer:
x= 45°
y= 90°
Step-by-step explanation:
x= angles on a straight line add up to 180°. 180°-135° = x.
y= x+y=135° & x =45°
135°- 45° = y

You must first simplify the radicals by taking out any perfect squares.
√8 + 3√2 + √32 =
√4 * √2 + 3√2 + √16 * √2 =
2√2 + 3√2 + 4√2 =
9√2
5 ( x + 3) = 6x - 3
5x + 15 = 6x - 3
x = 18 <====== this is the number

Answer:
(0,-5)
Step-by-step explanation:
3(4x+4y=20)
-3x-12y=-60
12x+12y=60
-3x-12y=-60
9x=0
x=0
4(0)+4y=-20
4y=-20
y=-5
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) in our case:
s(n)=3(1-4^n)/(1-4)
s(n)=-(1-4^n)
s(n)=(4^n)-1 and s=1023
(4^n)-1=1023
4^n=1024
n ln4=ln1024
n=(ln1024)/(ln4)
n=5
