In ΔIJK, j = 940 inches, ∠J=20° and ∠K=50°. Find the length of i, to the nearest inch.

5170 inches

Step-by-step explanation:

To solve this problem, we need to figure out a.), the angle measurement of I, and b.), the amount of inches per degree, which will lead us to c.), the final answer.

1) Add the measurements of J and K.

20 + 50 = 70

2) Subtract from 180 to find the measurement of I

180 - 70 = 110

∠I = 110°

3) Divide 940 by 20 to find the amount of inches per degree.

940/20 = 47

4) Multiply 47 by 110 to get the measurement of I.

47 * 110 = 5170

Final answer: I = 5170 inches
