Hello I need help with the following questions, I will rate your answer thank you!

1. Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. (If an answer does not exist, enter DNE. Round your answers to one decimal place. Below, enter your answers so that?B₁is smaller than?B₂.)

a=73, b=105, ?A=21 Find angle B1,B2,C1,C2 Find sides b1,b2

2. Use the Law of Sines to solve for all possible triangles that satisfy the given conditions. (If an answer does not exist, enter DNE. Round your answers to one decimal place.)

a=109, b=89, ?A=138 Find angle B1,B2,C1,C2 Find sides b1,b2

3. Solve triangleABC. (If an answer does not exist, enter DNE. Round your answers to one decimal place.) b=65, c=37, ?A=72 find a= , ?B= , ?C=

4. Find the indicated angle?. (Use either the Law of Sines or the Law of Cosines, as appropriate. Assumea=115andc=145. Round your answer to two decimal places.) ?= ?
