PLEASE HELP!<br> solve for x and then find measure for angle b
Bezzdna [24]
<h3>Answers:</h3><h3>x = 12</h3><h3>Angle B = 45 degrees</h3>

===========================================================

Explanation:

Angles A and B are alternate exterior angles.

Due to the parallel lines, alternate exterior angles are congruent

A = B

5x-15 = 2x+21

5x-2x = 21+15

3x = 36

x = 36/3

x = 12

Use this x value to find the measure of angle B

angle B = 2x+21

angle B = 2*12+21

angle B = 24+21

angle B = 45 degrees

As a check,

angle A = 5x-15

angle A = 5*12+15

angle A = 60-15

angle A = 45 degrees

Since A and B are both 45 degrees, this confirms the correct x value

Find the measure of C to the nearest degree.
Alisiya [41]

Let the ∠C be : θ

From the figure, We can see that the Side which is opposite to angle θ is measuring 7 units

Also, We can notice that Hypotenuse is 11 units

As we are dealing with opposite and hypotenuse, we can clearly use Sinθ to find out the angle θ

We know that :

\bigstar \ \ \boxed{\sf{Sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}

\implies \sf{Sin\theta = \dfrac{7}{11}}

\implies \sf{\theta = Sin^{-1}\bigg(\dfrac{7}{11}\bigg)}

\implies \sf{\theta = 39.52^{\circ}}

<u>Answer</u> : The measure of ∠C to the nearest degree is 38°

What expression is not equivalent to 2/3 *4.
Gelneren [198K]

Answer:

Step-by-step explanation:

Any expression that says (2 * 4)/3 is correct, even though there is a shift in the brackets. That means that A, B, C are all the same thing, and all are correct.

Only D is lying.

2*(1/3) = 2/3

4*(1/3) = 4/3     Now we have to add them

2/3 + 4/3 = 6/3 = 2

To show what the real answer is, try A

2*4/3

8/3  is the actual answer.
