What is the length of missing side DE? Round answer to nearest tenth.

Step-by-step explanation:

Considering the given triangle QED, to determine ED, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

ED/SinQ = EQ/SinD = QD/SinE

Therefore

ED/Sin 49 = 2/Sin 35

Cross multiplying, it becomes

EDSin35 = 2Sin49

0.574ED = 2 × 0.755

0.574ED = 1.51

ED = 1.51/0.574

ED = 2.63 in

correct

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
