I'm confused because there are no boxes, but maybe 2/4 3/6 5/10
Answer:
1. 98.7 km
2. 303.5 degree
Step-by-step explanation:
Using the alternate angle, the angle at B will be 50 + 10 = 60 degree.
To calculate the length AC of the returning journey, use cosine formula to calculate it.
To find the bearing of the returning journey, use sine rule to calculate it.
Please find the attached file for the solution
It will be easier to understand this using a venn diagram :
Answer:
the measure of the angle is 72
x=36
Step-by-step explanation:
we can make an algebraic equation using the info given
2x+80=152
2x=72
x=36
the measure of the angle is 72
Answer:
120c²d - 1200cd² -10c + 100d
Step-by-step explanation:
We will first of all evalute inide the bracket then we expand it.
(10c6d-5)(2c-5d4)
=(60cd-5)(2c-20d)
= 60cd*2c -60cd*20d -5*2c +5*20d
= 120c²d - 1200cd² -10c + 100d
