Elvis is trying to get fit for a Marathon. He wants to run 45km. Each week. This week he has runs of 7.5km,10.25,6.4km 12.8 km. How many more Kilometers does he need to run to reach his goal for the week

8.05 km

Step-by-step explanation:

just add everything together then subtract by 45

7.5+10.25+6.4+12.8=36.95 45-36.95=8.05

the answer is 45 i just did it on oddesy ware

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
