Answer:
m<U =
Step-by-step explanation:
From the given question, it can be observed that angles U and W are supplementary. These are angles that add up to .
So that;
<U + <W =
(8x + 9) + (8x - 5) =
16x + 4 =
16x = - 4
16 x = 176
x =
=
The measure of angle U = (8x + 9)
= 8(11) + 9
= 88 + 9
=
Thus, the measure of angle U is .
<h2>Answer:</h2><h2>The rate of depreciation of the car is 14%</h2>
Step-by-step explanation:
The price of car purchased 5 years ago = 15000
The price of car sold = 7000
By compound depreciation,
... (1)
where Pn = 7000
P = 15000
R = rate of interest to be calculated
T = 5 ( number of years)
substituting the values in equation (1), we get
0.858 is rounded off as 0.86
R/100 = 0.14
By simplifying the above equation, we get
Rate of depreciation = 14%
