Please help! The pitch of a roof is its slope. Find the pitch of the roof shown.

The pitch of a roof is 20 feet.

Step-by-step explanation:

Given :- height and base of a roof are 12 feet and 16 feet

To Find :- pitch of a roof

Solution :- Let the pitch of roof be x feet

Now, by using pythagoras theorem

h² = b² + p²

(x)² = (16)² + (12)²

x² = 256 + 144

x² = 400

x = √400

x = 20

so, x = 20 feet

Hence , the pitch of a roof is 20 feet

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
