Alvin is 6 years younger than elga. the sum of their ages is 92. what is elga's age?

Elga's age be 49 years

Step-by-step explanation:

Let Elga's age be x years

Then, Alvin's age will be (x - 6) years

The sum of their ages is 92

Therefore,

x + (x - 6) = 92

x + x - 6 = 92

2x - 6 = 92

2x = 92 + 6

2x =  98

x = 98 /2

x = 49 years

Hence,

Elga's age be 49 years

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.
