You will have to use the SAS postulate :))
35/4
You'd start by dividing 4 into 3. Since three is smaller it will not work. So you then divide it into 35. 35/4=8.75
Answer:
Find length opposite to 30deg
Opposite = tan(30)*42
= 24.2
Whole side = 24.2+10
Find angle of 0 + 30deg: (say x)
Tan(x) = 33.2/42
Arctan(0.79) = x
x = 38.3
The angle to find:
38.3-30:
8.3
The angle is 8.3deg.
probably 1 and 2, I'm only in 6th grade tho so I forgot (love the pfp btw)
The geometric mean of 8 and 12 is approximately 9.79796
