Step-by-step explanation:
the line x = -9 had only one valid x value (-9), but then all values for y between -infinity and +infinity are valid.
does this sound familiar ?
it should, because the y-axis is the same type of line.
it is x = 0.
so, x = -9 is simply parallel to the y-axis.
and any line perpendicular to it (crosses the original line in a right angle = 90 degrees) is then parallel to the x-axis.
there the situation is upside-down: there is only one valid y value, and all values between -infinity and +infinity are valid x values.
since the specified point on that line has y = 1, it means that the whole line is
y = 1

Find the measure of the indicated angles.show work.complete sentence a. m<QRP = ____
b. m<QRX = ____
The measure of m<QRX and m<QRP are 129 and 51 degrees respectively.
The sum of the interior angle of a triangle is 180 degrees, hence;
m<QPR + m<QRP + M<PQR = 180
Substitute the given parameters
49 + m<QRP + 80 = 180
m<QRP + 129 = 180
m<QRP = 180 - 129
m<QRP = 51 degrees
The sum of interior angle is equal to the exterior
m<QPR + M<PQR = m<QRX
m<QRX = 49 + 80
m<QRX = 129 degrees
Hence the measure of m<QRX and m<QRP are 129 and 51 degrees respectively.

The measures of the exterior angles of a heptagon are x°, 2x°, 3x°, 5x°, 7x°, 8x°, and 10x°. Solve for x.
Answer:
x = 10
Step-by-step explanation:
Exterior angles in any polygon always measure 360°
x + 2x + 3x + 5x + 7x + 8x + 10x = 360°
36x = 360
x = 360/36

Step-by-step explanation:
The relevant trig relations are summarized by the mnemonic SOH CAH TOA. This means ...
Sin = Opposite/Hypotenuse
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
So, for each triangle, determine the relationships of the given sides to the given angle: adjacent, opposite, or hypotenuse. Then write and solve the equation using one of the above templates.

An airplane has a wingspan of 20 feet and a length of 15 feet. If the model of this airplane has a wingspan of 8 inches, what is the length of this model?
Answer:
The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30
15x12=180
180/30=6.
Answer:
6 inches

I NEED HELP WITH GEOMETRY
Answer:
a) 136 square units
b) 92 square units
Step-by-step explanation:
A)
The triangle is worth:
16 * 16 / 2 = 128 + 16 * 16 / 2 = 128 = 256.
There is a rectangle in the middle with deletes 120 square units from 256.
256 - 120 = 136, so the first shape equals 136 square units.
B)
The smaller shaded triangles is 32 square units because 8 * 8 / 2 = 32.
The biggest one would be 15 * 8 / 2 = 60 square units.
32 + 60 = 92 square units.
Hope this helped!
Answer:
a. 136 [tex]units^{2}[/tex]
b. 92 [tex]units^{2}[/tex]
Step-by-step explanation:
a. Find the area of the triangle and the area of the rectangle, then subtract the area of the rectangle by the triangle.
Area of triangle: bxh / 2 = 32x16 / 2
= 512 / 2
= 256
Area of rectangle: bxh = 20 x 6
= 120
Total area: 256 - 120 = 136 [tex]units^{2}[/tex]
b. Just like a., find the area of the white triangle and the rectangle, then subtract the area of the triangle by the rectangle.
Area of triangle: bxh / 2 = 23x8 / 2
= 184 / 2
= 92
Area of rectangle: bxh = 23 x 8
= 184
Total area: 184 - 92 = 92 [tex]units^{2}[/tex]
