This equals 180.
1 and 3 are corresponding angles which means they are the same. 1+2=180 therefore 2+3= 180

From the figure we can observe that:

VS and UT lines are parallel to each other.

line ST is the transversal intersecting lines VS and UT making angles 2 and 3.

Here angles 2 and 3 are interior angles on same side of transversal.

If two lines are parallel and a transversal passes through them, then the pair of interior angles on the same side of transversal are supplementary that is they add up to make 180 degrees.

Applying this property to angles 2 and 3.

∠2 +3 =180°

Answer : 2 + 3 =180, last option is correct.

finlep [7]

Answer: the length is 11 cm.

The width is 7 cm.

Step-by-step explanation:

Let L represent the length of the rectangular plastic box.

Let W represent the width of the rectangular plastic box.

The area of the rectangular top of the box is 77 square cm. This means that

LW = 77- - - - - - - ;- - - -1

The plastic box has a length 4 cm longer than its width. This means that

L = W + 4

Substituting L = W + 4 into equation 1, it becomes

(W + 4)W = 77

W² + 4W = 77

W² + 4W - 77 = 0

W² + 11W - 7W - 77 = 0

W(W + 11) - 7(W + 11) = 0

W - 7 = 0 or W + 11 = 0

W = 7 or W = - 11

Since the width cannot be negative, then W = 7cm

L = 77/7 = 11 cm

In triangle UVW , the measure of angle W=90^ , the measure of angle U=31^ °, and UV = 31 feet. Find the length of VW to the near

Basile [38]

Answer:

Step-by-step explanation:

VW, also know as side X (as shown in image) can be found using the sine. Sin(theta)=opposite/hypotenuse. In this case, theta is 31 degrees and the hypotenuse is 31 feet. Plugging in all known values, we would have sin(31)=x/31. Rearrange the equation and isolate X on one side. Then use a calculator to find the answer. Good luck!
