Find the value of x y and z below !

Mathematics
1 answer:
ehidna [41]2 years ago

Answer:

x=67, y=121, z=65

Step-by-step explanation:

One property of parallelogram is that opposite angles have the same measure, so we can write down:

(y-9)=112\\y=121

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

(z+3)+112=180\\(x+1)+112=180

Solve the equations:

(z+3)+112=180\\z+115=180\\z=65\\(x+1)+112=180\\x+113=180\\x=67

To check, add up all 4 angles and check if they sum up to 360 degrees:

x=67, y=121, z=65\\(y-9)+(x+1)+(z+3)+112=360\\(121-9)+(67+1)+(65+3)+112=360\\112+68+68+112=360\\360=360

And please ignore the fact that I cannot insert the degree sign :(

Jose receives $1270 per year from three
salantis [7]

The answer is. $1500.

Let x represent the amount invested at 5%, then  is the amount invested at 8%, and  is the amount invested at 6%. Since the total return is $1270:

let money invested at 5%= x

money invested at 6%

= 20000- (X+X-1500)

21500-2x

Total interest for 1 year.

x×5/100+ (x-1500)×8/100+(21500-2x)×6/100 = 1270

5x/100+8(x-1500)/100+(21500-2x)6/100=1270

5x+8x-12000+129000-12x = 127000

x+117000 = 127000

x = 10000

money invested at 8%

=21500-2×10000

= 1500.

A ramp is used to load suitcases on an airplane. If the cargo door is 7 feet from the ground and the angle formed by the end of
melisa1 [442]

Answer: 16.56\ ft

Step-by-step explanation:

You must draw a right triangle as the one attached, where "x" is the lenght  in feet of the ramp.

You need to use the following Trigonometric Identity:

sin\alpha=\frac{opposite}{hypotenuse}

In this case you can identify that:

\alpha =25\°\\\\opposite=7\\\\hypotenuse=x

Now you must substitute these values into sin\alpha=\frac{opposite}{hypotenuse}:

sin(25\°)=\frac{7}{x}

Finally, you must solve for "x" in order to find its value.

This is:

sin(25\°)=\frac{7}{x}\\\\xsin(25\°)=7\\\\x=\frac{7}{sin(25\°)}\\\\x=16.56
