Natalie was supposed to use PEMDAS (as we all do when doing math), which stands for: Parentheses, Exponents, Mulitplication, Division, Addition, Subtraction. However, Natalie subtracted 1 from 2 before multiplying 6 by 4 and dividing it by 2.
Hope this helps!!

In analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.
<h3>What is the value of sin∠L?</h3>
Given that angle ONM is a right angled triangle, we can find length of OM using the Pythagorean theorem.
c = √( a² + b² )
OM = √( 4² + 3² )
OM = √( 16 + 9 )
OM = √25
OM = 5
Next, angle OML is also a right angled triangle, we can get the hypotenuse LO.
c = √( a² + b² )
LO = √( OM² + ML² )
LO = √( 5² + 12² )
LO = √( 25 + 144 )
LO = √169
LO = 13
Now, to get sin∠L, we use the mnemonic: SOHCAHTOA
sinθ = opposite / hypotenuse
sin∠L = OM / LO
sin∠L = 5/13
Therefore, in analyzing the given diagram which is a combination of two right angle triangle, the value of sin∠L is 5/13.

Answer:
-0.6 cm/min
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh
Solving for the base, we find ...
b = 2A/h
Then the rate of change of the base is ...
b' = 2(A'h -Ah')/h^2
Filling in the given values, we find the rate of change of the base to be ...
b' = 2((2 cm^2/min)(20 cm) -(160 cm^2)(1 cm/min))/(20 cm)^2
= 2(40-160)/400 cm/min
= -0.6 cm/min
The base is decreasing at 0.6 cm/minute.
