Solve the right triangle. Round decimal answers to the nearest tenth.
AnnZ [28]

Answer:

See solution below

Step-by-step explanation:

According to pythagoras theorem

hyp^2 = opp^2 + adj^2

10^2 = 4^2 + b^2

100 = 16 + b^2

b^2 = 100-16

b^2 = 84

b = √84

b ≈ 9

Using SOH CHA TOA identity

sin B = AC/AB

Sin B = 9/10

B = arcsin0.9

B ≈ 64degrees

sinA = BC/AB

Sin A = 4/10

A = arcsin0.4

A ≈ 24degrees

If i have 2 apple and get 3 more then lose 2 how many do i have left
nydimaria [60]
You have 2 apples, get 3 more, and then lose 2 of them.

So, you HAVE 2 apples, and if you get 3 more, you can add it to the 2.
2 + 3 = 5

In total at the moment, you have 5 apples. Now, you lose 2 more. We can subtract that from our total number of apples.
5 - 2 = 3

We now know that you are left with 3 apples.

What pattern do you see in the powers of 4?
Over [174]
All of them are even numbers. You will not find a power of 4 that is an odd number. Also, all of the numbers have a 4 or a 6 or both. For example,
4^3= 64

4^8= <span>65536


I hope this helps:)</span>
