Yo sup??
a.For this part just draw a triangle with sides 4,8 and 8 inches respectively.
The sides having 8 inches should make equal angle with the base side.
b.One angle is 20
The other two angles be x and y
but x=y because its an isosceles triangle
x+y+20=180
2x=160
x=80
Hope this helps.
When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99.
For example, 4/11 = 36/99 = 0.36 with bar notation over 36.
Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6.
You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal.
Example: 2/4 = 0.5
Answer:
the x is 3 and the y is -3
Step-by-step explanation:
Known :
w = 12 feet
h = 18 feet
V = 3.240 feet³
Asked :
l = ...?
Answer :
V = l × w × h
3240 = l × 12 × 18
3240 = 216 l
l = 3240 ÷ 216
l = <u>1</u><u>5</u><u> </u><u>feet</u>
So, the length is 15 feet

Answer:
Step-by-step explanation:
x+y=17 is NOT the equation for any circle. You have omitted the exponents. The equation for the circle should be
x^2 + y^2 = 17.
:::::
Plug the coordinates of D into the equation.
(-4)² + (-1)² = 17, so D is on the circle.
Plug the coordinates of E into the equation.
1² + 4² = 17, so E is on the circle.
:::::
Slope of DE = (-1 - 4)/(-4 - 1) = 1
Slope of perpendicular to DE is -1.
Midpoint of DE: ((-4+1)/2, (-1+4)/2) = (-1.5, 1.5)
Point-slope equation for perpendicular bisector:
y-1.5 = -(x+1.5)
y = -x
:::::
Center of circle is (0,0)
0 = -0, so y=-x passes through the center.
