Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
Answer:
Step-by-step explanation:
y = (x+1)² - 3
= (x²+2x+1)-3
= x²+2x-2
:::::
y = (x-2)² + 3
= (x²-4x+4) + 3
= x²-4x+7
Answer:
(5x+4)=114(vertically opposite angle)
5x=114-4
x=110/5
x=22
(3x-24)+(2y)+144=180(sum of straight line angle)
(3X22-24)+(2y)=180-144
(66-24)+2y=36
42+2y=36
2y=36-42
y=(-6)/2
y=-3
A=LW and we are told that:
A=x^2-100 and W=x-10 so:
x^2-100=L(x-10)
L=(x^2-100)/(x-10) factoring the numerator...
L=((x+10)(x-10))/(x-10) the (x-10) terms cancel out leaving...
L=x+10
$148-$123= 25 is the answer to your equation above
