Answer:
48°
Step-by-step explanation:
In triangle CYZ, angles Y and C are complementary, so ...
(5x +22) + (12x) = 90
17x +22 = 90
17x = 68
x = 4
The angle of interest is 12x° , so has measure
12·4° = 48°

Answer:
Speed = 1050 meters per seconds
Distance =10500 meters
Step-by-step explanation:
Car traveling at a speed of 63 kilometers per hour
Let us convert this into meter per second
Speed = 
kilometers per hour
Speed = 
--------(A)
1 kilometer = 1000 meters
1 hours = 3600 seconds
Replacing them in (A)
Speed = 
Speed = 
meters per seconds
Speed = 
meters per seconds
Speed = 1050 meters per seconds
Distance = speed x time
Speed = 1050 mt per sec
time = 10 sec
Distance = 1050 x 10 = 10500 meters

Answer:
Total combination = 180,180
Step-by-step explanation:
It is a combination based problem.
So,
Total people = 13
Group = 3,6,2,2
So,
For 6 people
13C6= 1,716
For 3 people
7C3 = 35
For 2 group of 2 people
(4C2)/2 = 3
Total combination = 1,716 × 35 × 3
Total combination = 180,180
