Answer:
1 》let equal side be X and other side y
now, length of y= 2x sin teta/2
=12.3×sin42/2
=12.3 × sin21
=4.407
r/q= sin y
I got sin y,
or option one
Hope this helps ;3
Answer:
Step-by-step explanation:
We first let 0.38 (8 being repeated) be T.
Since z is recurring in 1 decimal places, we multiply it by 10. 10z = 3.88
Next, we subtract them. 10 r T 3.88 0.38 9x 3.5
Lastly, we divide both sides by 9 to get IC as a fraction. 3.5 T 9 35 90 7 18
