In a triangle , the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 100 m

madam [21]

Answer:

The three unknown angles X, Y , and Z are:

X = 40, Y = 20, and Z = 120

Step-by-step explanation:

Let's name X the measure of the first angle, Y the measure of the second one, and Z that of the third one.

Then we can create the following equations:

X = 2 Y

Z = 100 + Y

and

X + Y + Z = 180

So we use the first equation and the second one to substitute for the variable X and Z in the thrid equation:

2 Y + Y + (100 + Y) = 180

4 Y + 100 = 180

4 Y = 80

Y = 80/4 = 20

Then X = 40, Y = 20, and Z = 120

a ladder 30 decimeters long is leaning against the side of a building. the ladder makes an angle of 25 degrees with the side of

ozzi

H=how far up from the ground does the ladder touch the building
h/30=sin 25°
h=30 sin 25°
h=12.7 decimeters(1 decimal place)
Answer: The height that the ladder touch the building far up from the ground is 12.7 decimeters.

Kristen is 64 inches tall, and she stands 12 feet away from a streetlight. If she casts an 82-inch-long shadow, how tall is the

o-na [289]

Answer:

176.39 inches or

14.70 feet

Step-by-step explanation:

Consider the right triangle made by Kristen, ground and shadow.

This triangle has one leg as 64 inches.

Next consider the right triangle formed by street light, ground upto shadow tip.

The two triangles have common angle of elevation and also another angle as 90 degrees.

Hence the two triangles would be similar

Also if A is the angle made by hypotenuse of both triangles with the ground we have

$tanx=\frac{64}{82}$

This value also equals by bigger triangle as

$tanx=\frac{h}{82+12(12)}=\frac{h}{226}$

From these two we get

h = height of street light = $\frac{226(64)}{82} =176.39$

Determine if the rates $168 rasied for washing 24 cars and $280 rasied for washing 40 cars are equivalent

Mariana [72]

We are given : $168 raised for washing 24 cars and $280 raised for washing 40 cars.

We know the rate formula.

Rate = Total amount ÷ Total numbers.

Let us find value of each rate for the given problem.

Rate 1: Total amount ÷ Total numbers = $168 ÷ 24 = $7.

Rate 2: Total amount ÷ Total numbers = $280 ÷ 40 = $7.

We can clearly see that Rate 1 is equal to Rate 2, that is $7.

So, we can say rates are equivalent.

)The equation of the line of best fit of a scatter plot is y = −4x − 6. What is the the y-intercept?

Gekata [30.6K]

Well the y-intercept is where a line crosses the y-axis
y=-4x-6
think of it as y=mx+b
m is always going to be your slope
b is always going to be your y-intercept
y-intercept of y=-4x-6
is -6
