Answer:
The correct answer AC = 11.52
Step-by-step explanation:
From the figure attached with this answer shows the triangle ABC.
BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees
To find AC
From the figure we can see that D is the mid point and AD⊥BC
Then BD = CD = 4/2 = 2 cm
<BAD = 10° and <CAD = 10°
By using trigonometric ratio,
sin 10 = CD/AC = 2/AC
AC = 2/sin 10 = 2/0.1736 = 11.52
Therefore the value of AC = 11.52 cm
Answer:
12 units²
Step-by-step explanation:
ABCD is a parallelogram.
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 12 and h = 1, thus
A = 12 × 1 = 12 units²
Answer:
2
Step-by-step explanation:
The answer is 2
I believe your answer is required in Rise/Run form.
Rise is -1 and Run is +2
so
-1/2
We assume that
if xy=0
x and y=0
first make it equal to zero
minus 5 on both sides
4x^2-12x+4=0
undistribute 4 for ease
4(x^2-3x+1)=0
since 4 does not equal zero, and the only thing that will get it to zero is 0,
x^2-3x+1=0
use quadratic equation
if you hahve
ax^2+bx+c=0
x=

1x^2-3x+1=0
a=1
b=-3
c=1
