As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others
8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^
Answer:
348 in^2
Step-by-step explanation:
8 x 9 = 72
6 x 8 = 48
9 x 6 = 54
72 + 72 + 48 + 48 + 54 + 54
348
I think to number you can add to get -34 are -14 and -20
