Answer:
F= 180 - (127°+33.5°)
180- 160.5
= 19.5°
Step-by-step explanation:
Angles in a triangle add up to 180°
t=45min
d=4km
45min/60min = 0.75 hours
v=d/t
v=4km/0.75hours
v=5.33km/hour. So the answer is B. 45 minutes.
Answer:
54
Step-by-step explanation:
BEDMAS
z=10
(10)3-3(2-10)
=(10)3-3(-8)
=30-(-24) *2 negatives = a positive
=30+24
=54
-15+5x= 20
5x= 35
x= 7
20= -15+5x
35= 5x
7 = x
