Answer:
SW = 151°
Step-by-step explanation:
The secant- secant angle TUV is half the measure of the intercepted arcs, that is
∠ TUV = 
(SW - TV ) , substitute values
6x - 19 = ( 12x - 5 - (2x + 7 ) ) ← multiply both sides by 2 to clear the fraction
12x - 38 = 12x - 5 - 2x - 7
12x - 38 = 10x - 12 ( subtract 10x from both sides )
2x - 38 = - 12 ( add 38 to both sides )
2x = 26 ( divide both sides by 2 )
x = 13
Then
SW = 12x - 5 = 12(13) - 5 = 156 - 5 = 151°
Yes, that is the famous first Pythagorean triplet: 3²+4²=5²
or
For three lengths to be able to form a triangle, it suffices that every one of those lengths is shorter than the sum and longer than the difference of the other two.
It is enough to check just one side.
So,
3 + 4 > 5
4 - 3 < 5
Your triangle is constructible.
Answer:
the mean number is 2.7
Step-by-step explanation:
if you add up the frequency of books then divide by 20 you get 2.7
Answer:
Step-by-step explanation:
6 2/5 cookies in 4 mins
To find the unit rate in minutes, divide 6 2/5 and 4 by 4.
In one minute is 1.6 cookies.
To find the unit rate in cookies, we divide by 6 2/5.
For one cookie, there are 5/8 minutes.
