4. A ladder 7m long leans against a building to reach a window 5.8m above the ground. Include a diagram with your solutions. a) What angle does the ladder make with the ground? Round to the nearest degree. b) How far is the foot of the ladder from the base of the building? 5. Aria is in a hot air balloon and her two friends, Beta and Calvin, are on the ground below. The angle of elevation from Beta to the balloon is 21°, the angle of elevation from Calvin to the balloon is 34°. If Beta and Cal are standing 20 km apart what is the height of the balloon? Label the triangle and add all relevant values from the question. d) 320 18 x 4.7 30°

solve these questions for me please with accuricy + detail
also use any of the following methods:
sin = opp/hyp
cos = adj/hyp
tan = opp/adj
sinA/a = SinB/b = SinC/c
a/SinA = b/sinB = c/SinC
a^2 = b^2+c^2 - 2bcCosA
CosA = b^2+ c^2 - a^2/2bc
