The values are vx =
, vw =
and m∠x = 45°, for the given right angle diagram.
Step-by-step explanation:
The given is,
Right angled triangle XVW,
XW = 14
m∠V = 90°
m∠W = 45°
Step:1
Given diagram is right angle triangle,
Trigonometric ratios for right angle is,
∅
............................(1)
∅
.........................(2)
∅
..........................(3)
Step:2
For the value of VX,
∅ 
From given,
∅ = 45°
XW = 14
Above equation becomes,
45 
Where, Sin 45 =
,

Step:3
For the value of VW,
∅ 
From given,
∅ = 45°
XW = 14
Above equation becomes,
45 
Where, cos 45 =
,

Step:4
For the value m∠x = a,
a 
From given,
VX = 
VW = 
Above equation becomes,
a 
a = 1
a =
(1)
a = 45°
m∠x = a = 45°
Step:5
Check for solution,
m∠v = m∠w + m∠x
= 45° + 45°
90° = 90°
Result:
The values are vx =
, vw =
and m∠x = 45°, for the given right angle diagram.
-- Driving at 30 mph for 20 minutes (1/3 hour), you cover 10 miles.
-- Walking at 3 mph for 10 minutes (1/6 hour), you cover 0.5 mile.
-- Average speed = (total distance covered) / (time to cover the distance)
= (10.5 miles) / ( 1/2 hour)
= 21 miles per hour.
Answer:
Step-by-step explanation:
reading_rate: 2.5R = 1250
R = 1250/2.5 = 500 pages/hr or ( 1 hr)/(500 pages)
Solve for hr?
=( 1 hr)/(500 pages) * 1250 pages
now, cancel out pages and we are left with hours
= 1250/500 hours
= 2.5 hours
