Find the missing angel ​

Mathematics
1 answer:
kolezko [41]3 years ago

Answer:

x=25°

Step-by-step explanation:

The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:

x+y=90

Insert the known values:

x+65=90

Solve for x. Subtract 65 from both sides:

x+65-65=90-65\\\\x=25

The missing angle, x°, is 25°.

:Done

X - y =2 X + y= -3<br> What is (x,y)
Dimas [21]

Answer:

(-1/2,-5/2)

Step-by-step explanation:

x-y = 2

x+y = -3

---------------

Through Elimination, we can just add the system of equations. The y cancels out and gives us the single equation for x:

2x = -1

x = -1/2

Substitute -1/2 for x in either equation and you get:

(-1/2) + y = -3     Solve for y

y = -5/2

Students heights in inches were obtained as part of a study and a frequency distribution was constructed with the first class ha
polet [3.4K]
The frequency of the second class is 6.

Since the class width is 6 and the lower limit of the first class is 50, this means the first class goes from 50-55.  This would put the second class at 56-61.  There are 6 data points in this set that would go in the second class.

7.For tire size P225/45R17, give the following: Width(mm): _______________ Aspect Ratio (%): _______________ Height (in.): _____
irakobra [83]

The width is the first numbers.

Width = 225 mm

Aspect ratio is the second number.

Aspect ratio is 45

Aspect ratio is width / height.

You have the ratio and width so you can calculate the height:

Multiply the width by the ratio:

Height = 225 x 0.45 = 101.25 mm

101.25/25.4 = 3.98 inches

The rim

Diameter is the last number

Rim diameter = 17 inches

So the overall height would be approximately 17 + 3.98 + 3.98 = 24.96 inches

Round the answers as needed.
