Answer:
The bear is 35 years of old now.
Step-by-step explanation:
Leon wanted to know the age of the black bear at the zoo.
He is informed that if he adds 10 years to the age of the bear and then doubles it, the bear would be 90 years old.
Let the present age of the bear is x years.
So, according to the above condition we can write
2(x + 10) = 90
⇒ 2x + 20 = 90
⇒ 2x = 70
⇒ x = 35
So, the bear is 35 years of old now. (Answer)
There is a theorem that states that the two triangles made from connecting a rectangles opposing vertices produces two identical triangles. you can then use the cpctc theorem to prove the angles are congruent. it can also be proven by using the hypotenuse-leg theorem; US=SU because of the symmetric property, RU=ST because RUTS is a rectangle and therefore its parallel sides are congruent, ∠URS and <span>∠UST are right because RUTS is rectangular, therefore triangleUSR=triangleSUT because of the hypotenuse leg theorem, </span>∠USR=<span>∠SUT becuase of CPCTC</span>
