Find each marked side or angle and show the step by step​

a. sind=8/15

d=sin¹(8/15)

d=32.2°

b. tan70=3.8/y

ytan70=3.8

y=3.8/tan70

y=1.38cm

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
