The length of the mirror is 64.52 cm
<u>Explanation:</u>
Given:
Distance of the person from the mirror = 145cm
Angle of depression = 14°
Angle of elevation = 11°
Vertical dimension of the mirror = ?
For angle of elevation:
For the angle of depression:
Total length of the mirror, AC = AB + BC
= 28.275 + 36.25cm
= 64.52 cm
Therefore, the length of the mirror is 64.52 cm
Which of these numbers are divisible by 9? 7,625 4,932 9,180 2,969 9,180 and 4,932 2,969, 9,180, and 7,625 9,180 and 7,625 2,969

Answer:
The answer to your question is below:
Step-by-step explanation:
A number is divisible by 9 if the sum of all the individual digits is evenly divisible by 9.
7,625 example 7 + 6 + 2 +5 = 20 it's not divisible by 9
4,932 4 + 9 + 3 + 2 = 19 it's not divisible by 9
9,180 18 it is divisible
2,969 26 it's not divisible by 9
9,180 18 it is divisible
4,932 18 it is divisible
2,969 26 it's not divisible by 9
Answer: 4.
Step-by-step explanation: In this case it is easier to imagine it on the number line: the y coordinates are the same, so the distance is only in x direction. On the positive side it is 2 2/3 to zero and on the negative, 1 1/3 to zero. Total is 1 1/3 + 2 2/3 = 4. Or the proper writing: 2 2/3 - (-1 1/3) = 4
Answer:
A)60°
Step-by-step explanation:
a straight line is 180° then
if a line bisect it in to a half it become 90°
then
the exterior angle of a triangle is equal to the sum of two interior angles
this means 150°-90°=60°
Answer:
Amir's car will cost £10348.88 after 23 years.
Step-by-step explanation:
I finally found a UK human!
This is compound interest so you have to find a decimal multiplier and multiply that with £16470 to the power of 23.
The decimal multiplier would be 0.98. This is because you do 100% - 2% as depreciating basically means a decrease, which gives you 98% and then you divide that by 100 to get your decimal multiplier - 0.98.
16470 × 
= £10348.88
I hope that helps you!! ^-^
