Angle A = angle U since they're both right angles (both 90 degrees). This is what the square marker means.

segment AC = segment UW

Angle C = angle W because they have the same angle marker

---------------------

we have two pairs of congruent angles, with segments between them that are congruent. So we use the ASA property

The final answer is choice E.

-2|x-4|+7=-3 how do i solve this absolute value problem

ira [324]

Let's do this step by step:
Subtract both sides by 7
-2|x-4|= -10
Divide each side by -2
|x-4|= 5
Now since this is an absolute value equation, you will have two answers. This means you make the equation both positive and negative.
X-4= 5and -(x-4)= 5
Solve for x for both
X-4= 5: add four on both sides
X= 9
-x+ 4= 5: subtract 4 and divide by -1
X= -1
So your answer is: X= -1 , 9

How to find the arc length (geometry)

andrew11 [14]

Answer:

94.2

Step-by-step explanation:

Arc length is basically circumference.

Circumference formula: 2πr

All we need is the radius.

Radius = r

15 x 2 = 30 (diameter)

Then we are going to multiply by pi.

Arc length = 30π OR 94.2

Using the unit circle find the exact value. CSC -30º =

AlexFokin [52]

Answer:

csc (- 30)° = - 2

Step-by-step explanation:

Using the trigonometric relationship

csc x = $\frac{1}{sinx}$ and the exact value sin30° = $\frac{1}{2}$

sin(- 30)° = - sin30° = - $\frac{1}{2}$ , thus

csc (- 30)° = $\frac{1}{-\frac{1}{2} }$ = - 2
