Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)
Chain rule
y=f(g(x))
y´=(d f(gx)/d g)(d g/d x)
or
y=y(v) and v=v(x), then dy /dx=(dy/dv)(dv/dx)
in our case:
y=sin (v)
v=arcsin(x)
dy/dv=d sin (v)/dv=cos (v)=cos(arcsin(x)
dv/dx=d arcsin(x)/dx=1/√(1-x²)
dy/dx=[cos (arcsin(x))]/√(1-x²)
Answer: d sin(arcsin(x))/dx=[cos (arcsin(x))]/√(1-x²)
The answer is 12
Step 1. Perform the operations inside the parenthesis:
(4 + 9) − 3(6) ÷ 2 + 8 = 13 - 18 ÷ 2 + 8
Step 2. Division has advantage over subtraction and addition:
13 - 18 ÷ 2 + 8 = 13 - 9 + 8
Step 3. Subtract and add:
13 - 9 + 8 = 12
$27.00x.15=4.05
27.00+4.05=$31.05
$31.05/3= 10.35
Each person will pay $10.35
Answer:
See Below
Step-by-step explanation:
Since they are lines, and if two lines have angles that are congruent, then it has to be perpendicular. Angles sum up to 180, and since they are equal, it is 90.
