Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
Answer:
Step-by-step explanation:
The original distance that Angel wanted to walk will be represented as A
Since we don't know the additional distance Angel walked it'll be represented as B
A= the amount of distance Angel wanted to walk
B= the amount of distance Angel wanted to walk past his/her challenge goal
C= the amount of distance Angel walked originally from to past her/his challenge goal
A+B=C
Example:
I decide to work for A hours today as a challenge. Within this time I'm working I decided to extend my goal another B hours.
Answer:
y= -2/10 +2
Step-by-step explanation:
Answer:
-1/3x+3 = x-1
Step-by-step explanation:
The solution is (3,-2)
Check and see if the point solves the equation
-1/3x+3 = x-1
-1/3(3) +3 = 3-1
-1+3 = 3-1
2=2 yes
<u><em>Answer:</em></u>
Area of triangle = 12 units²
<u><em>Explanation:</em></u>
<u>Area of triangle is calculated using the following rule:</u>
Area = 0.5 * base * height
Now, in the given figure each square represents one unit, therefore, we will get the lengths by counting squares
Base = BC = 8 units
Height is the perpendicular distance from vertex A to the base BC = 3 units
<u>Substitute with these values in the above equation to get the area as follows:</u>
Area = 0.5 * 8 * 3 = 12 units²
Hope this helps :)
