Which is the length of the building's wall brace? A. 14.45 m
B. 17 m
C. 23 m
D. 49 m
E. 189 m

A) 14.45 m is the answerrrerreer

17m

Step-by-step explanation:

We can use  the Pythagorean theorem

a^2+b^2= c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 = c^2

64+ 225 = c^2

289 = c^2

Taking the square root of each side

sqrt(289) = sqrt(c^2)

17 =c

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

its line 2 i just added the rest or else it wouldn't let me answer
