9 3/4 x 15 1/2
= 151 1/8
or
= 151.125
Angle B = 56.309932474020215
This is through using a trigonometry calculator I forgot how to set it up tbh.
Hope this helps ;)
For extra info Angle C = 33.690067525979785.
They add up to 90 which added with the right angle of 90 means the interior angles add to 180 meaning it is in fact correct because a triangle is always 180 inside.
I'll answer ur question but the image is blurry
The answer is 3.75 or 15/4 or 3 3/4
