Please helppp meee out

9

Step-by-step explanation:

10p+12p+5p+148+149

27p+297=540

I got the 540 because it has five angles -2 equals three triangles * 180 equals 540

Subtract 297

27p=24

divide by 27

P=9

9°

Step-by-step explanation:

Sum of the interior angles of any polygon is given = (n-2)180°

where n is the no. of sides

Sum of the interior angles= (5-2)180= 3×180°=540°

Therefore, 10p+12p+149°+148°+5p= 540°

=>27p+ 297°= 540°

=> 27p= 243°

=> p= 243°/27

=> p= 9°

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
