Alright, so since the slope of the perpendicular line is -1/(slope), we get (-1/2)=-1/2 and y=(-1/2)x + something. Plugging 7 in as y and -4 in as x, we get 7=(-1/2)(4)+something (let's make it a variable b), and multiplying it out we get 7=-2+b. Adding 2 to both sides, we get 7+2=9=b, so the perpendicular line equation is therefore y=(-1/2)x+b<span />
Answer:
32.1
Step-by-step explanation:
0.53x=17
x=32.1
Step-by-step explanation:
first, the other 2 angles in the triangle must be equal.
and they must both be complementary to 180 degrees for the 108 degree angle.
180 - 108 = 72 degrees.
so, we have 72, 72 and m degrees as degrees in the triangle.
the sum of all the angles in a triangle is always 180 degrees.
72 + 72 + m = 180
144 + m = 180
m = 36 degrees
