The roof of a home rises vertically by 7 ft through a horizontal distance of 15 ft. Find the pitch (slope) of the roof. i need this asap will mark brainilest

Step-by-step explanation:

First, we need to know the formula for the slope of the roof. The formula is the following

Pitch= Rise / Run

Slope of the roof is referred to the ratio of the vertical measurement which is the rise to horizontal measurement which is the run. Using the given above let's find the pitch of the roof.

Given:  Rise= 7 ft    Run= 15 ft

Slope = Rise/Run

         = 7 ft / 15 ft  

         = 0.47

The slope is 0.47ft

hope this helped!

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
