The slope of line XY: m = - 2/3
The slope of a line perpendicular to XY:
m1 =
![\frac{-1}{ \frac{-2}{3} }= \frac{3}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-1%7D%7B%20%5Cfrac%7B-2%7D%7B3%7D%20%7D%3D%20%20%5Cfrac%7B3%7D%7B2%7D%20%20%20)
m 1 =
1.5
The sum of acute angles in the right triangle is 90 degrees
smaller<span> acute angle = 3x
</span><span>larger acute angle = 7x
</span>
3x + 7x = 90
10x = 90
x = 90/10
x = 9
larger acute angle = 7x = 7*9 = 63°

Answer:
<h2><em>
[2(x+y)-25]cm</em></h2>
Step-by-step explanation:
Let the height of their oldest sister isabella be z centimeters. Roger is x centimeters tall and Olivia is y centimeters tall.
If their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia's height, this can be expressed as shown;
First let us get the sum of Roger and Olivia's height;
The sum of Roger and Olivia's height = (x+y)cm
The double of the sum of their ages = 2* (x+y)cm = 2(x+y)cm
Now if Isabella, is 25 centimeters shorter than the double of the sum of their ages, the expression will be [2(x+y)-25]
<em>Since the height of isabella is z, the expression that model isabella's height will be expressed as z =[2(x+y)-25]cm</em>
