Two lines intersect at a point, forming ∠1 , ∠2 , ∠3 , and ∠4 .

1 answer:

3 0

The answer is 30. if 1 is 120 then that means 2 is 60 and vertical angles go to 90 so it would have to be 30 to get to 90. I hope this helped:)

Please help me with this problem, please

Answer:

sin(x) = 5/13

cos(y) = 5/12

Therefore, sin(x) = cos(y)

Step-by-step explanation:

Trig ratios:

$sin(\theta)=\dfrac{O}{H}\\\\\\cos(\theta)=\dfrac{A}{H}\\\\\\tan(\theta)=\dfrac{O}{A}$

where $\theta$ is the angle, O is the measure of the side opposite the angle, A is the measure of the side adjacent to the angle and H is the hypotenuse, of a right triangle

We have been given the measures of the two legs, so we can find the measure of the hypotenuse by using Pythagoras' Theorem $a^2+b^2=c^2$

(where a and b are the legs and c is the hypotenuse of a right triangle)

$\implies 5^2+12^2=c"\\\\\implies 169=c^2\\\\\implies c=\sqrt{169}\\\\ \implies c=13$

Now we can use the trig ratios:

$\implies sin(x)=\dfrac{5}{13}$

$\implies cos(y)=\dfrac{5}{13}$

Therefore, sin(x) = cos(y)

3n² + 2n - 8=0<br> Solve each equation with the quadratic formula

8_murik_8 [283]

Answer:

-2,4/3

Step-by-step explanation:

ax²+bx+c=0

$x=\frac{-b \pm\sqrt{b^2-4ac} }{2a} \\3n^2+2n-8=0\\n=\frac{-2\pm\sqrt{2^2-4*3*(-8)} }{2*3} \\n=\frac{-2 \pm \sqrt{4+96}}{6} }\\n=\frac{-2 \pm 10}{6} \\n=\frac{8}{6} =\frac{4}{3}\\or~n=\frac{-12}{6}=-2$

A school baseball team earned $3416.90 from selling 5716 tickets to their game. If grandstand tickets sold for 65 cents each and

horsena [70]

Answer:

1194 bleacher tickets

Step-by-step explanation:

If all were grandstand tickets, revenue would be 0.65*5716 = 3715.40. It was actually 298.50 less than that. Each bleacher ticket sold drops the revenue by .25, so there were 298.50/.25 = 1194 bleacher tickets sold.

You deposit $50 in your savings account. One week later, you withdraw $20. Write each amount as an integer

Lerok [7]

Depositing means that you added 50$ to your account. This means that you account increased by an amount of 50.
The integer describing this is +50.

Then, withdrawing means that you took money from the account. This means that your account decreased by an amount of 20.
This can be expressed as a -20 integer.
