Answer:
8.485
Step-by-step explanation:
This is a right isosceles triangle, thus the angles for side a and b are going to be the same, all the angles must all add up to equal 180, thus 180 - 90 = 90 then 90 ÷ 2 = 45 so we now know that angle a and b are 45°, with that said we can now find out what the vale of x is.
Calculates 2 sides based on 3 given angles and 1 side.
a = c·sin(A)/sin(C) = 8.48528 = 6
b = c·sin(B)/sin(C) = 8.48528 = 6
Area = = 36
Perimeter p = a + b + c = 28.97056
Semiperimeter s = = 14.48528
Height ha = = 8.48528
Height hb = = 8.48528
Height hc = = 6
Median ma = = 9.48683
Median mb = = 9.48683
Median mc = = 6
Inradius r = = 2.48528
Circumradius R = = 6
