Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
Answer:
x=9.89
Step-by-step explanation:
since both missing sides are equal, we give length x to both.
then, using the Pythagorean theorem, a²+b²=c², we get:
x²+x²=14²
we aolve for x:
2x²=14²
x²=14²/2
x=sqrt(14²/2)=9.89
Answer:
hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
From diameter you get radius by halving the diamter
radius = 14/2 = 7 cm
volume, height, and radius of a cylinder are all related by formula for volume of cylinder:
V = <span>πr²h
If we want to solve for h, we divide both sides by </span><span>πr² and get
h = V/(</span><span>πr²)
since V = 112</span><span>π and r = 7, h is equal to
h = (112</span>π)/(<span>π*7²) = 112/49 = 16/7 cm
height is C 16/7 cm
