Answer:
can you explain yourself more please
Answer:
answer is c
Step-by-step explanation:
a) To find the missing side length on triangle A, we can use the Pythagorean theorem.
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5 cm
5 and 12 = 5 and 12
b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.
Hope this helps!! :)
Given that:
Consider it is
instead of 10 on two places.
is between 3 and 4. So, Beau thinks a good estimate for
is = 3.5.
Solution:
To find
, Beau found 3² = 9 and 4² = 16.
He said that since 10 is between 9 and 16.
Since 10 is close to 9, therefore
must be close to 3. So, Beau's estimate is high.
Now,


Since, 10 lies between 9.61 and 10.24, therefore
must be lies between 3.1 and 3.2.

Therefore, the estimated value of
is 3.15.
