Solving a is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known. square polygon triangle problem

option: C is correct (i.e. Triangle)

Step-by-step explanation:

Solving a is the process of calculating unknown side lengths or angle measures of a triangle if certain of the side lengths and/or angle measures are known.

Triangle is correct; because To SOLVE A TRIANGLE means to know all three sides and all three angles.

Hence option : C is correct

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

i think asking google will you get the answer to that question
