Answer:
Applying cosine theorem:
AB = sqrt(AC^2 + BC^2 - 2 x AB x BC x cosC)
= sqrt( 72^2 + 135^2 - 2 x 72 x 135 x cos(119deg))
= 181
Applying sine theorem:
BC/sinA = AB/sinC
=> sinA = BC x sinC/AB
=> A = arcsin(BC x sinC/AB)
= arcsin( 135 x sin(119deg)/181)
= 40.7 deg
Hope this helps!

Step-by-step explanation:
Answer:
r = 32
Step-by-step explanation:
R is the variable that we are trying to find.
24 = 3/4r
Since r is being multiplied by 3/4, we need to divide 3/4 on both sides to "undo" the multiplication.
24 / 3/4 = 3/4r / 3/4
32 = r
Therefore, r = 32.
To check, we can plug 32 into the equation.
24 = 3/4 x 32
3/4 x 32 = 24
