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.

5x + 2y = 3 2x+3y=-1 Solve

professor190 [17]

Answer:

x = 1

y = -1

Point = (1,-1)

Step-by-step explanation:

2x + 3y = -1 = y = -2/3 - 1/3

5x + 2(-2/3 - 1/3) = 3

5x - 1 1/3 - 2/3 = 3

5x - 2 = 3

+2 +2

5x = 5

x = 1

2(1) + 3y = -1

2 + 3y = -1

-2 -2

3y = -3

y = -1

Diane sold t-shirts at a festival and made a profit of $84 . She made $6 for each t-shirt she sold. Her total expenses were $30.

sweet-ann [11.9K]

Answer:

9 t-shirts

Step-by-step explanation:

Well if she made a profit of $30 that would mean that you would subtract $84-$30 which would give you $54. Than you would divide 54/6 to find how much t-shirts she sold.

-Hope this helped (this is one of the first questions ive answered )

Plsssssss help got 20 mins the question is: The sin of angle DCB is

Elena L [17]

Answer:

i. <DCB = $53.13^{o}$

ii. Sin of <DCB = 0.8

Step-by-step explanation:

Let <DCB be represented by θ, so that;

Sin θ = $\frac{opposite}{hypotenuse}$

Thus from the given diagram, we have;

Sin θ = $\frac{4}{5}$

= 0.8

This implies that,

θ = $Sin^{-1}$ 0.8

= 53.1301

θ = $53.13^{o}$

Therefore, <DCB = $53.13^{o}$ .

So that,

Sin of <DCB = Sin $53.13^{o}$

= 0.8

Sin of <DCB = 0.8

PLEASE HELP ME WITH GEOMETRY <3

prisoha [69]

Answer:

answer is 25

Step-by-step explanation:

EKJ = 90, same as JHF, and EJK is 65 (because EJF =115 and 180-115=65

65+90=155

180-155=25
