PLEASE ANSWER THIS FOR ME

Step-by-step explanation:

Once again it is trigonometry

and this time we have sides o and h valued but not a

Therefore we do not need a and are using the formula triangle o/sin*h

But we have to change this into sin=0/h to get the answer

sin=o/h

sin=19/49

sin=0.3

then now we click the 2nd function button or shift and sin with the value 0.3

this gives us 17.4

answer=17.4

23°

Step-by-step explanation:

sin ∠N= OP/NO= 19/49

⇒∠N ≈ 23°

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
