solving a triangle MNL
M=36°
N=?
L=83°
m=?
n=?
l=29
for angle N,
M + N + L=180°
or,36°+N+83°=180°
or, N=180°-36°-83°
or,N=61°
for side m, we have,
(m/sinM) = (l/ sinL)
or, m/sin36°=29/sin83°
or, m=( 29×sin36°)/sin83°
or, m= 17.17
similary, you can find out the value of n by using relation (mnn/sinN) = (l/ sinL) and solve triangle PQR
finding the area
we have,
area of triangle(A)=1/2×ab×sin C
where C is angle and a, b are sides
so area of first triangle is,
A=0.5×21×16×sin30=84 square feet
a
Area of another triangle can be findout in the same way
Answer:
y = 4x +4
Step-by-step explanation:
-12x + 3y = 12
3y = 12 +12x ......bring x to opposite side and sign changes
y = 12 +12x / 3 .............bring 3 to oppsite side and it would divide
y = 4 + 4x ............result of diving and the answer of ours
y = 4x +4
19+(-19)=0
Step-by-step explanation:
So first lets simplify this. We can use the method keep,change, change to do this. Keep the value of positive 19. Then change the + sign to - and the - sign to plus which gets us
19-(+19).
We can remove the +since we know its positive leaving 19-19 which is 0
