CUADERNO DE TRABAJO 1 - QUINTO GRADO Ejercicios:
Resuelva los siguientes problemas, en su cuaderno.
1. Cristina recibe a su abuela cada 15 días y a su tío cada 18 días. Un
dia le toco escribir a ambos. ¿Dentro de cuantos días le tocara volver
a escribirles el mismo día?
2. Se van a repartir equitativamente 90 cuadernos y 72 lápices entre la mayor ca

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
