In PQR, Q = 76, PQ = 18, and QR = 27<br> Can you help me with 5!
SashulF [63]

Answer:

The answer is

m<p =66°21'14"

m<R =37°38'46"

PR =28,6

Step-by-step explanation:

{pr}^{2}  =  {18}^{2}  +  {27}^{2}  - 2 \times 18 \times 27 \cos(76)  = 817.85 \\ pr = 28.6 \\  \cos(p)  =   \frac{ {18}^{2}  +  {28.6}^{2} -  { {27}^{2} }  }{2 \times 18 \times 28.6 } = 0.4 \\ m < p = 66.42 \\ m < r = 180 - 76 - 66.42 = 37.58

x- y = (1)(x - y) → True

x - y = 1 + (x - y) → No solution, False

x - y = (6 - 5)(x - y)  → True
