Answer:
x = 26
Step-by-step explanation:
it is a right angle so
(x+4)3=90
3x+12=90
-12 -12
3x = 90-12
3x = 78
/3 /3
x = 26
Answer:
Step-by-step explanation:
Given that cesar left the college traveling 12 mph. Then, 4 hours later, Gabriel left traveling the same direction at 24 mph.
Before Gabriel started Cesar would have travelled for 4 hours
So distance travelled by Cesar in 4 hours 
Thus Cesar is ahead of Gabriel by 48 miles
Difference of speed 
So to catch Cesar time required = 48/difference in speed
= 4 hours
It will take 4 hours.
Answer: 7
Step-by-step explanation:
Answer:
(8x + 1)° + ( 4x+11)° = 180° (linear pair )
8x +1 + 4x +11 = 180
8x + 4x + 1 + 11 = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x= 168/12
x = 14
