The intersection of three altitudes of a triangle is
called the orthocenter, while altitude is the line drawn from one of the vertex
of a triangle and extends it in such a way that it cuts perpendicularly the opposite
side of the same triangle.
<span> For obtuse
triangle, the orthocenter always lies outside of the triangle. So option “C” is
correct. </span>
<span>An image of obtuse triangle along with orthocenter is
attached herewith.</span>

Answer:
y = -2/3x + 23/3
Step-by-step explanation:
Let equation of the line be y = mx + c
m = (3-5)/(7-4) = -2/3 gradient/slope formula
sub (4, 5)
5 = -2/3 (4) + c
c = 23/3
therefore, equation of the line is y = -2/3x + 23/3
Hope it helps! :)
This is a topic called coordinate geometry. If you would like to find out more you can follow learntionary on instagram. I'll be posting some notes on coordinate geometry soon and I'll also post other useful math stuff as well :)
15,000 + (400 * 12)(0.25) + 200(3.53) =
15,000 + 4800(0.25) + 706 =
15,706 + 1200 =

Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
substitute x=3
Answer:
33 meters
51 meters
Step-by-step explanation:
84-18= 66
66/2= 33
