D there is really no solution unless u get the value of x which I do not have so it can only be simplified into this equation above I hope this is correct and helpful
Answer:
It is 6.5 meters
The centimeter practical unit of length for many everyday measurements. A centimeter is equal to 0.01(or 1E-2) meter.
Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120 km
b=70 km
β=28 degrees (
∘)
b^2=(a^2)+(c^2)−2ac*cosβ
70^2
=(120^2
)+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )
(c^2
) −211.907c+9500=0
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500
D=(q^2
) −4pr=(211.907^2
)−4⋅1⋅9500=6904.75561996
D>0
=
(−q±
)/2p=(211.91±)/2
=105.95371114±41.5474295834
(−147.501140726)(−64.4062815596)=0
=147.501140726
=64.4062815596
Hope it helps you........
