Answer:
4
Step-by-step explanation:
Factor the two given numbers into primes.
12: 2 * 2 * 3
8: 2 * 2 * 2
They both have 2 * 2 in common.
The highest common factor is 4
Answer:
please last option
using 45 degree as reference angle
using tan relation
Tan45=perpendicular /base
1 = x\6
x = 6
now using right angled triangle relation
H²=p²+b²
then h²= 6²+6²
H = √36+36
H =6√2
therefore y=6√2
Answer:
2704
Step-by-step explanation:
Answer:
EcD= 52 DCB=128
Step-by-step explanation:
First, let's find out what x equals and what (x+11) equals
And therefore...
Now angle ecd is a vertical angle we just found.
So angle ECD= 52 degrees
And agles ECD and DCD and supplimntary
