10+20+30+40+50+60+70+80+90+100=

550

Step-by-step explanation:

10+20+30+40+50+60+70+80+90+100=550

10+20 = 30 + 30 = 60 + 40= 100 + 50 = 150 + 60 = 210 + 70 = 280 + 80 =

360 + 90 = 450 + 100 = 550

answer

d. 10

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,

8+10
