Solve this image using Sine Law
Law of Sines:a/sin A = b/sin B = c/sin C
Put in the values we know:a/sin A = 7/sin(35°) = c/sin(105°)
Ignore a/sin A (not useful to us):7/sin(35°) = c/sin(105°)
Now we use our algebra skills to rearrange and solve:
Swap sides:c/sin(105°) = 7/sin(35°)
Multiply both sides by sin(105°):c = ( 7 / sin(35°) ) × sin(105°)
Calculate:c = ( 7 / 0.574... ) × 0.966...
c = 11.8 (to 1 decimal place)

Solve this image
Start with:sin R / r = sin Q / q
Put in the values we know:sin R / 41 = sin(39°)/28
Multiply both sides by 41:sin R = (sin(39°)/28) × 41
Calculate:sin R = 0.9215...
Inverse Sine:R = sin−1(0.9215...)
R = 67.1°

If you're writing down an angle of a triangle with angles A, B and C how do you write it?
Depending on the angle it will be written differently, but when describing the angle you are talking about, put it in the middle. For example say I want to write the specifc answer for angle B being 36o. I would write it like this.
<ABC = 36o
Or if I wanted to say angle C = 24o I would write it like...
<BCA = 24o
