Point g is the centroid of the right △abc with m∠c=90° and m∠b=30°. find ag if cg=4 ft.

Explanation:  

Please follow the diagram in attachment.  

As we know median from vertex C to hypotenuse is CM  

We are given length of CG=4  

Median divide by centroid 2:1  

CG:GM=2:1  

Where, CG=4

ft

Length of CM=4+2= 6 ft

Using trigonometry ratio identities

Using pythagoreous theorem  

Length of AG=2/3 AN

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
