Answer: $83.\overline{3}\text{ feet}$

Step-by-step explanation:

Since, In the given diagram,

The sides of the triangles ABC and EDC are,

BC = 62 feet, DC = 93 feet and DE = 125 feet(given)

And, angles B and D are right angles,

⇒ $\angle ABC\cong \angle EDC$

$\text{Also, } \angle ACB\cong \angle ECD$ ( Vertically opposite angles )

By AA similarity postulate,

$\triangle ABC\sim \triangle EDC$

The sides of similar triangles are in same proportion ,

⇒ $\frac{AB}{ED}=\frac{BC}{DC}$

⇒ $AB \times DC = BC \times ED$

⇒ $AB = \frac{BC.ED}{DC}$

By substituting the values,

We get,

⇒ $AB = \frac{62\times 125}{93}$

⇒ $AB = \frac{7750}{93}=83.\overline{3}\text{ feet}$

The first term of an arithmetic sequence is 123 the common difference is 12 and the sum is 1113 how many terms are in the series

S_A_V [24]

You can use this formula of arthenatic series to find sum to get the number of term
sum= n÷2 (2a+(n - 1)d)
n= number of tern = n
a= first term =
d= common difference
sum= 1113
you can find the number of series by putting in them

In triangle ABC, angle A is 25 degree, and Angle B is 105 degrees. what is the measure of angle c

Scilla [17]

Angle c= 60°

This is because 105+25+x=180°
Hope this helps and good luck!! :)
