I need help with this​
ddd [48]

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3

What dose this equal (8.5)x(-3)=a
Nana76 [90]

Answer:

-25.5

8x3=24

but we still have the .5 so we multiply that by 3 which equals to 1.5 add that to 24 which makes 25.5 and because only one of the numbers was negative it turns 25.5 into -25.5.

Hello!

<u><em>Answer: </em></u>

<u><em>1. =-6</em></u>

<u><em>2. =39</em></u>

<u><em>3. =-603</em></u>

_________________________________________________

Explanation: This question's it's about the order of operations. It stands for p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right. (PEMDAS)

1. -4(3-1)+2

Do parenthesis first.

(3-1)=2

-4*2+2

Then do multiply left to right.

-4*2=-8

Add left to right.

-8+2

8-2=6

*Answer should be have negative sign.*

Answer: → \boxed{=-6}

______________________________________________________

2. 3⋅[(30−8)÷2+2]

Do parenthesis first.

(30-8)=22

22/2+2

Then divide left to right.

22/2=11

Add left to right.

11+2=13

Multiply left to right.

3*13=39

*Answer should be have positive sign.*

Answer: → \boxed{=39}

_____________________________________________________

3. 14(1-23)2+13

Do parenthesis first.

(1-23)=-22

14(-22)*2+13

Then, you multiply left to right.

14(-22)=-308

-308*2=-616

Add/subtract left to right.

-616+13

616-13=603

*The answer must be have a negative sign*

Answer: → \boxed{=-603}

____________________________________________________________

Hope this helps!

Thank you!

Have a great day!
