Answer:
Im having a good day, im glad yours is good aswell!
Step-by-step explanation:
2/5g=3/5
multiply both sides by the reciprocal of 2/5
g=(3/5) (5/2)
g=3/2
The sum of their ages is 71+68=149
They are actually 149 years old
Pythagorean theorem:
AB = √30^2 + 16^2 = 34
These are similar triangles.
∠BAC is congruent to ∠BAD
∠ACB is congruent with ∠ABD (both right angles)
Using ratios:
AC / AB = AB / (AC + CD)
AC + CD = AB² / AC
CD = AB² / AC - AC
CD = 34² / 16 - 16
CD = 56.25
The answer to this question is 56.
