From a point 80m from the base of a tower, the angle of elevation to the top of the tower is 28 degrees how tall is the tower

The height of the tower is 42.54 m.

Solution:

The reference image of the answer is attached below.

Given data:

BC = 80 m, ∠C = 28°

Multiply by 80 on both sides, we get

42.536 = h

Switch the sides.

h = 42.536

h = 42.54 m

The height of the tower is 42.54 m.

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
