icang [17]

Answer:

26°

Step-by-step explanation:

AC=tan 64

BC=x=sec 64

Using sine rule

(Sin 64)/tan 64 = (sin BAC)/sec 64

Cos 64 = (sin BAC)(cos 64)

Sin BAC= 1

BAC=90

ACB+ 64+90=180

ACB= 26°

Can someone please help me with this math question .
Alona [7]

No, Yes, No, Yes

using the laws of exponents

(1)

(4^{3})³ = 4^{9}

4³ × 4³ = 4^{6}

4^{9} ≠ 4^{6} → No

(2)

(3^{4})^4 = 3^{16}

3^{8} × 3^{8} = 3^{16} → Yes

(3)

18^{8} = (6 × 3 )^8 = 6^{8} × 3^{8} ≠ 6^{4} × 3^{4} → No

(4)

20^{3} = (4 × 5 )³ = 4³ × 5³ → Yes

Write this number in standard form. 300+80+0.9+0.06+0.001
Lina20 [59]

Hey there! I'm happy to help!

First, let's add the hundreds and the tens.

300+80=380

We see that there is nothing in the ones place, so we keep our ones place 0 and we move onto adding the tenths.

380+0.9=380.9

We add the hundredths.

380.9+0.06=380.96

And finally, we add the thousandths.

380.96+0.001=380.961

Therefore, this number in standard form is 380.961.

Have a wonderful day! :D
