Answer:
Step-by-step explanation:
The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.
Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality
15<5x-3<17
Add 3 to this inequality
15+3<5x-3+3<17+3
18<5x<20
Divide it by 5:
The height of the square pyramid exists 2 units.
<h3>How to estimate the area of the base of the square pyramid?</h3>Volume of the square pyramid
where B exists in the area of the base H lives at the height of the pyramid
we have H = 6
V = 70
substitute in the formula and solve for B, we get
B =
= 35
To estimate the height of the square prism
Volume of the square prism = Bh
Where B exists the area of the base
h exists the height of the prism
we have B = 35 and V = 70
substitute in the formula and solve for h
70 = (35)h
h = 2 units.
