Answer:
x =48.6
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp side / hypotenuse
sin x = 54 /72
Taking the inverse sin of each side
sin ^ -1( sin x) =sin ^-1 ( 54/72)
x = 48.59037789
To the nearest tenth
x =48.6
Answer:
4 km/h
Step-by-step explanation:
We are told that Dina and Masha started out on a 10 km bike path at the same time.
Dina's biking speed is 5 km/h.
Let us find taken by Dina to cover 10 kn distance.
Therefore, Dina took 2 hours to complete 10 km.
Since both started at the same time, therefore, Masha also took 2 hours to complete 2 km less than Dina.
Let us find distance covered by Masha.
Now let us find Masha's biking speed.
Therefore, Masha's biking speed is 4 km per hour.
Answer:
1. B.
2. A, E.
3. D.
Step-by-step explanation:
1. 8.225 ÷ 5 = 1.645
2. 892 ÷ 8 = 111.5
8920 ÷ 80 = 111.5
894 ÷ 10 = 89.4
89.2 ÷ 0.08 = 1115
8.92 ÷ 0.8 = 11.15
0.892 ÷ 0.008 = 111.5
3. 4367 ÷ 0.004 = 1,091,750
<span>When 3 Triangle sides are known:
</span><span>The longest side must be less than the sum of the other 2 sides.
5, 12 and 13 - can be constructed
</span>2, 11 and 15 <span>- can be constructed
3, 7 and 11 - CAN'T be constructed - the longest side is greater than the sum of the other two.
4, 8 and 15 </span><span>- CAN'T be constructed - the longest side is greater than the sum of the other two
