Find the measure of angle y. Round your answer to the nearest hundredth. Right triangle
e-lub [12.9K]
<h3>The measure of angle y is 35.68 degrees</h3>

<em><u>Solution:</u></em>

Given that,

hypotenuse 12

Opposite 7

Find the measure of angle y

y is unknown and is between the hypotenuse and adjacent side

The figure is attached below

In a right triangle, the sine of the angle is the ratio of the side opposite to the angle to the hypotenuse

Therefore,

sin\ y = \frac{opposite}{hypotenuse}\\\\sin\ y = \frac{7}{12}\\\\sin\ y = 0.5833\\\\y = sin^{-1}\ 0.5833\\\\Use\ arcsin\ calculator\\\\y = 35.6829 \\\\y \approx 35.68

Thus measure of angle y is 35.68 degrees

Quadrilateral ABCD is given, the interior angle at vertex B is 97 degrees and the exterior angle at vertex A is 88 degrees. Line
Citrus2011 [14]

Answer:

angle 1 = 83°

angle 2 = 88°

Step-by-step explanation:

angle 1 and angle on vertex B are

pair of co interior angles ( whose sum = 180° )

so, angle 1 + angle B = 180°

angle 1 = 180° - angle B

angle 1 = 180° - 97° = 83°

hence, angle 1 = 83°

but, angle 2 and exterior of vertex A forms alternate interior angle pair ,

so , angle 2 = angle A = 88°

i hope you got it ....

3 cans store 9 tennis balls. Write an equation to represent the realationship
LUCKY_DIMON [66]

Answer:

y = 3x.

Step-by-step explanation:

To find out the equation, put it this way. For every 3 cans, there are 9 tennis balls. So if you put it as 9/3, that means that for every can, there are 3 tennis balls. y = 3x. The x is the variable for how many cans there are. If there are 5 cans, the five would multiply by 3 and then thats your answer.

I hope I helped.

Brainliest would be appreciated.

Have a nice day.

What is the vertex of the parabola whose equation is y = (x + 1) ^2+ 3
lora16 [44]

Answer:

The vertex is (-1, 3)

Step-by-step explanation:

The form this is in is called vertex form. We can express the equation using its base form.

y = a(x - h)^2 + k

Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
