Answer:

x = 22.5°

Step-by-step explanation:

The interior angle at E is (180 -4x), the supplement of the exterior angle there, 4x. The sum of angles 2x and (180-4x) will be equal to 6x, because alternate interior angles at transversal BE are congruent:

2x +(180 -4x) = 6x

180 = 8x . . . . . . . add 2x and simplify

22.5 = x . . . . . . . divide by 8

The value of x is 22.5°.

25% of what number is 15. Can u please explain how you solved it. Thanks :)

Ilya [14]

60.
let x be the number you're trying to solve.
(x/100)25 = 15
x/4 = 15
x = 15(4)
x = 60

Answer:

12. 5x

13. 5/x-z

Step-by-step explanation:

12. product means multiplication so multiply 5 by x= 5x

13. quotient means division and difference means subtraction. so you divide 5 by x-z= 5/x-z

boyakko [2]

Answer:

5 meters.

Step-by-step explanation:

Given:

Mr. Dyer is leaning a ladder against the side of his house to repair the roof.

The top of the ladder reaches the roof, which is 3 meters high.

The base of the ladder is 4 meters away from the house, where Mr. Dyer's son is holding it steady.

Question asked:

How long is the ladder?

Solution:

Here we found that a right angle triangle is formed in which base and height is given and we have to find the longest side of the triangle.

Base = 4 meters

Height = 3 meters

Length of the ladder = ?

By Pythagoras theorem:

Square of longest side = Square of base + Square of height

$(Longest\ side)^{2} = 4^{2} +3^{2}$

$(Longest\ side)^{2} = 16+9$

$(Longest\ side)^{2} = 25$

Taking root both side :-

$\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{25}$

$Longest\ side = \sqrt[2]{5\times5} \\ Longest\ side = 5$

Thus, length of ladder is 5 meters.
