Answer:
Perpendicular x = 7 unit Approx.
Step-by-step explanation:
Given:
Right angle triangle
θ angle = 45'
Hypotenuse = 10
Find:
Perpendicular x
Computation:
Sin θ = Perpendicular / Hypotenuse
Sin 45 = Perpendicular / 10
0.70 = Perpendicular / 10
Perpendicular x = 7 unit Approx.
Answer:
⇒Let the no. of call minute be = x
⇒& no. of text messages be = y
⇒As total number of minutes used and text messages sent last month was 561
So x + y = 561.................................(1)
⇒Now as call minutes cost 8 cents each and text messages cost 5 cents each and her bill was $34.26
So 8x + 5y = 3426............................(2)
On solving equation 1 & 2 we have
we got x = 354 cent
& y = 207 cent
Well you would want to get y alone so multiply both sides by 4 to cancel out the division and you will find that your slope is 4
