I'll draw a quick sketch. It's hard to "see" this kinda of problem w/o a drawing , so start there. just draw as much as you can from what the problem tells you.

diameter = 14 cm

radius = 7 cm

pi = 3.142

PRQ = 35 °

to find Y use law of sines

sin(70) / Y = sin(55) / 7

sin(70) / sin(55) / 7 = Y ( I'll use my calculator for all the non standard angles )

sin(70) * 7 / sin(55) = Y ( and invert and multiply the fraction in the denom )

8.03007 = Y

x = 70 °

if you have questions, and you should, just put them in the comments , I'll see them later :)

Y + 0.5xy = x + 2; x = 1<br> How do you solve for y

vfiekz [6]

Step-by-step explanation:

replace the value of x with 1

y + 0.5 × 1 × y = 1 + 2

do the maths

y + 0.5y = 3

here the value of y is equal to 1. same goes for x, if we have no given value for them.

1.5y = 3

y = 3/1.5

y = 2
