Answer:

I'd say 42 degrees, but I might be wrong.

Step-by-step explanation:

It looks the same as the other labeled angle, which is 42 degrees, so that would make angle b 42 degrees.

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we find the diameter ((h)) of the rectangle on the floor using the Pythagorean theorem.

So we have :

${h}^{2} = {a}^{2} + {b}^{2}$

${h}^{2} = 64 + 9$

${h}^{2} = 73$

$h = \sqrt{73}$

_________________________________

Step (2)

Now we another using of Pythagorean theorem for finding d :

${d}^{2} = {h}^{2} + {c}^{2}$

${d}^{2} = 73 + 16$

${d}^{2} = 89$

$d = \sqrt{89}$

$d = 9.4$

And we're done.

Thanks for watching buddy good luck.

I’m very confused, my teacher did not explain well.

Sauron [17]

In order for two triangles to be considered as similar, they must be
- equiangular (all angles equal)
- all sides equal (sss)
- if two pairs of two sides are in proportion or are matching, and one included angle is equal

Q4a) yes, because all the angles are equal (equiangular)

b) yes, because all sides are in matching ratio (so 10/5 is 2, 6/3 is 2 and 8/4 is 2; so they are in matching ratios)

c) yes, because if you plus 60 and 70, you get 130. Minus 180 and 130, you get 50. So, in both triangles the angles will be 60,70 and 50; so they're equiangular

Julius is studying populations of robins in the local area. He counts 12

AleksAgata [21]

Well, he recaptured 3 out of the 7 he marked. We can presume that the other 5 are gone. The population would be 8 robins, because 4 of the robins Julius marked were not recaptured. Therefore, the population is around 8-10 robins.

Luis wants to know how much he will have available to spend on his trip to Belize in three years if he deposits $2700 today at a

ad-work [718]

Use the compound amount formula: A = P(1+r)^t

Here, A = $2700(1+0.07)^3 = $3307.62

Luis will have accumulated $3307.62 to spend on his trib to Belize.
