Using the triangle, we can find the angle lengths and using those and trig ratios, find the side lengths. Lets say the top side length is "y".
Using the Law of triangles, we can find the missing angle from 180-90-70=20 deg.
Then we can use the Law of sines,
sin(70)/13=sin(20)/y
y=sin(20)*13/sin(70)
y=15.34
Finally, we use the Pythagorean Theorem, (13)^2+(15.34)^2=x^2
x = 20.1
Answer:
i cant really see take a closer picture plz
Step-by-step explanation:
Multiply 9 and 5 then multiply by .5 giving you 22.5 so I’d say that’s your best option
Average speed: distance traveled/elapsed time
= 75/30
= 2.5 meters per second.
Best of Luck!
