Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer

The mistake he made was that he did not consider units of measurement while comparing the lengths
He has to convert the both quantities into the same unit to compare the lengths either centimeters to meters or meters to centimeters
Step-by-step explanation:
Length of desk = 1 meter
Henry's name tag = 8 cm
Henry says that his name tag is 7 cm longer than the desk. The mistake he made was that he did not compare the units of both quantities. He just subtracted 1 from 8 and got 7. Meter is a larger unit and centimeter is a smaller unit. In order to compare the lengths of the desk and his name tag the units have to be same.
Hence
The mistake he made was that he did not consider units of measurement while comparing the lengths

Answer:
x=12
Step-by-step explanation:
Since AB=BD, they have equal length. 15x+4=2x+160, 13x=156, x=12
Well, the first thing we need to do is divide 10 by 4. These teo numbers are the number of pens, and cost of them. So,
================================
10 / 4 = 2.5
--------------------------------------------------------
Now we have to use the answer we got, 2.5 which is the cost of 1 pen, and multiply it by 7.
================================
2.5 x 7 = 17.5
--------------------------------------------------------
This means that 7 pens cost <span>£</span>17.5
