Question

can someone please help me with thisss??!

Answer 1

Answer:5.5

Step-by-step explanation:

x=7

z=10

Y=32°

cosine rule :

y^2=x^2+z^2-2xzcosY

y^2=7^2+10^2-2 x 7 x 10 x cos32

y^2=7x7 + 10x10 - 2x7x10x0.8480

y^2=49+100-118.72

y^2=149-118.72

y^2=30.28

Take the square root of both sides

√(y^2)=√(30.28)

y=5.5
