Since he can drive 160 kilometers in 2 hours, we can divide 160 by 2 to get 80.
160/2 = 80
Then we can take 3.5 • 80
To get 280 kilometers
Hope I helped ^u^
Answer:
Angle 1 = 48°
Step-by-step explanation:
The total of the angles 1,5, 4, 3 is 180 degrees = 2( 90 degrees) ( given)
So
< 1+ < 5+ <4 + < 3 = 180°
but , < 3= 42°
so < 1 + <5 + <4 = 180° - 42° = 138°
It can deduced that <5 + <4 = 90° (***)
so <1 = 138°- 90°= 48°
(***) when we draw four angles in such a way that their sum is 180 °. Then either the sum of the first two angles is 90 ° or the sum of the second and third angle is 90 °. Similarly the third or fourth angle is 90 ° or fourth and first angle is 90 °.
The diagram is given to elaborate this point
[1] = Vertical Angle Theorem
[2] = Converse of the same side interior angle theorem
The answer is A!
Hope this helps! :)
