<h3>What is a Triangle ?</h3>
A triangle is a polygon with three sides , three angles and three vertices.
According to the Proportionality Theorem
When a line is parallel to one side and intersects the other lines at two different points then it divides both the line in similar ratio.
As in the given figure DC is parallel to AP ,
then RD : DP = RC:CA
42:15 = x: 10
42/15 = x / 10
x = 42 * 10 /15
x = 28
Therefore the value of x is 28 .

Answer:
<h2>h < 2</h2>
Step-by-step explanation:
5(2h+8) < 60
Expand the terms in the bracket
We have
10h + 40 < 60
Group like terms
10h < 60 - 40
10h < 20
Divide both sides by 10
h < 2
