Answer:

72°

Explanation:

Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.

Using the rule of <u>Alternate Exterior Angle</u> theorem, x would equal to 72°.

Answer: 72

Now that we are told that J and K are parallel, we know that there can be a transversal line (m). You can see that m goes 72 degrees.

So, the answer is 72. Best of Regards!

Hi plz help me with this geometry question

Answer:

Approximately 54°

Step-by-step explanation:

So we know Angle A, the side opposite to Angle A, and the side opposite to Angle B (the angle we want to find). Given these circumstances, we can use the Law of Sines.

The Law of Sines states that:

$\frac{\sin(A)}{a} =\frac{\sin(B)}{b} =\frac{\sin(C)}{c}$

The variables do not really matter. Instead, it's more important that the angle corresponding to the side lines up with each other.

Anyways, since we know Side A, Angle A, and Side B, let's use the first and second ratios:

$\frac{\sin(A)}{a} =\frac{\sin(B)}{b}$

Plug in 80° for A, 11 for a, and 9 for b:

$\frac{\sin(80)}{11} =\frac{\sin(B)}{9}$

Cross multiply to solve for B:

$9\sin(80)=11\sin(B)$

Divide both sides by 11:

$\sin(B)=\frac{9\sin(80)}{11}$

Use the inverse sine function. And finally, use a calculator to solve:

$\angle B =\sin^{-1}(\frac{9\sin(80)}{11} )\\\angle B\approx53.6829\textdegree\approx54\textdegree$

Answer:

slope is 2

Step-by-step explanation:

first add -14x like...

-14x+7y=-9

+14x +14x

7y=14x-9

divide 7 by the who equation

7y=14x-9

y=2x-9/7

alex and Lara have $21.00 each to spend at a book fair, where all students receive a 35% discount. They both want to purchase a

storchak [24]

Alex is correct the book would cost $18.52 before taxes adding 10% tax the book would cost an additional $1.85 for a total of $20.37. This would be just under the $21.00 that both Alex and Laura had to spend. Laura tried to combined the 35% discount which you cannot do. So yes they both would be able to purchase the book.

11 15/26 + [-17 5/13] =

$11 \frac{15}{26} = \frac{301}{26}$
