The angle of B is \angle B=19^{\circ}

Explanation:

It is given that \angle A=120^{\circ} and a=8, b=3

To determine the \angle B, let us use the law of sine formula.

Thus, we have,

\frac{Sin A}{a} =\frac{Sin B}{b}

Substituting the values in the formula, we have,

\frac{Sin 120}{8} =\frac{Sin B}{3}

Multiplying both sides by 3,we get,

\frac{3(0.866)}{8} ={Sin B}

Simplifying and dividing, we get,

0.32475=Sin B

Multiplying both sides by \sin ^{-1}, we get,

\sin ^{-1}(0.32475)=B

Thus, B=18.95^{\circ}=19^{\circ}

Hence, The angle of B is \angle B=19^{\circ}

Was I right for 46 but 47 I need help with
Julli [10]
You are not right on #46. Since he is going 50 miles in 50 minutes, that means that he is going a mile a minute. That means in an hour, he will have gone 60 miles. That means he will have been going 60 mph, so the correct answer is (4)

I cannot help you with 47 because you did not include the picture it shows.

Please answer!!!! will make brainliest!!!
hammer [34]

Answer:

B

Step-by-step explanation:

1.

  • 3(x+3) - 2 < 4
  • 3x + 9 -2 < 4
  • 3x < 4-7
  • 3x < - 3
  • x < -1
  • x = (-oo, -1)

2.

  • 1 - x ≤ -1
  • - x ≤ -1 - 1
  • -x ≤ -2
  • x ≥ 2
  • x = [2, +oo)

Correct choice is B.

If f(x) = x2 - 2x and g(x) = 6x + 4 for which value of x does (t +g)(x)=0​
Vinil7 [7]

Answer:

-2

Assumption:

Find the value of x such that (f+g)(x)=0.

Step-by-step explanation:

(f+g)(x)=0

f(x)+g(x)=0

(x^2-2x)+(6x+4)=0

Combine like terms:

x^2+4x+4=0

This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.

(x+2)(x+2)=0

(x+2)^2=0

So we need to solve:

x+2=0

Subtract 2 on both sides:

x=-2

Let's check:

(f+g)(-2)

f(-2)+g(-2)

((-2)^2-2(-2))+(6(-2)+4)

(4+4)+(-12+4)

(8)+(-8)

0

0 was the desired output of (f+g)(x).
