Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
The total interest earned is 40.75 and the final balance is 65.75
<u>Solution:</u>
Given, principle amount P = 25
Interest rate
Times compounded per year n = 12
Time in years t = 30
On substituting the values we get
Interest I = A - P [since, A = P+I]
So if the number is positive then the opposite is negative, vice versa.
opposite of 4 is -4
opposite of -5 is 5
A sweater is on sale for $18.00 which is 50% off of its original price, to simply get the original price, you add 18 to itself, since 18 is the half of the original price, so to get the original price you have to add the missing 50% which is 18 as well, so you got $18.00 - 50% and another $18.00 - 50%. add them together you get $36.00, which is equivalent to 100%.
