WHERE ARE THE EXPERTS AND ACE!!!!!!! I NEED HELP PLS SHARE YO SMARTNESS!!!!! WILL GIVE BRAINLIEST AND RATE AND VOTE!!! EASY IM J
Charra [1.4K]

Answer:

7.2

Step-by-step explanation:

Apply Law of Cosines, given that b is 13.5, c is 8.9, and Angle a is 29.

{a}^{2}  =  {b}^{2}  +  {c}^{2}  - 2bc \cos(a)

{a}^{2}  =  {13.5}^{2}  +  {8.9}^{2}  - 2(13.5)(8.9) \times  \cos(29)

{a}^{2}  = 182.25 + 79.21 - 240.3 \times 0.8746

{a}^{2}  = 182.25 + 79.21 - 210.1711

a = 7.2
