What is the answer to the problem 21+40(2x-3)

12345 [234]

Answer:

x = 1.2375 or 99/90

Step-by-step explanation:

Step 1: Distribute

21 + 40(2x - 3)

21 + 80x - 120

Step 2: Combine like terms

21 + 80x - 120

80x - 99

Step 3: Solve for x

80x - 99 + 99 = 0 + 99

80x / 80 = 99 / 80

x = 1.2375

Answer: x = 1.2375 or 99/80

PLEASE HELP! ITS DUE SOON!!!! I DONT GET THIS!!

o-na [289]

Answer:

d. 50°

Step-by-step explanation:

Since you know one angle and its opposite side, use the law of sines.

sin 36°/11.9 = sin D/15.6

sin D = 15.6 × sin 36° / 11.9

sin D = =0.7705

D = sin^-1 0.7705

D = 50.4°
