Answer:
108
Step-by-step explanation:
Since angle AFB and angle BFC are next to each other and form a straight line, we can subtract 72 from 180 to get the missing angle measurement. (all straight lines add up to 180)
180-72=108
So 108 would be your answer
Nobody understands maths and if you do you were sent from heaven
Answer:
18:5???
Step-by-step explanation:
1 1/2hrs = 90 mins
90 / 5 = 18
25 / 5 = 5
I'd say: 18 : 5??
Answer:
<h2>n = -12</h2>
Step-by-step explanation:
2n + 5 = n - 7 <em>subtract 5 from both sides</em>
2n + 5 - 5 = n - 7 - 5
2n = n - 12 <em>subtract n from both sides</em>
2n - n = n - n - 12
n = -12
Answer:
1,Let us suppose that the height of the ladder is h and the horizontal distance of the ladder from the wall is d, then we use these two important trigonometric functions; the sine and the cosine.
h = sin 78 * 8 m and d = cos 78 * 8m where sin 78 = 0.9781 and cos 78 = 0.2079
With the given values, I expect you to do the two multiplications yourself. You will obtain a near to 8 m answer for the height h and a near to 1.7 m answer for the distance d.
2, The ship is 15 km from the port.
3,30m The ship must travel 15.6km 10 km 8. A rectangular field is 40 m long and 30 m wide. Carl walks from one corner of the field to the opposite corner along the edge of the field. Jade walks across the field diagonally to arrive at the same corner. Tip How much shorter is Jade's shortcut? Show your work. Sketch a diagram Carl-40m ade - b?= C² first. 40m. Jade = a't 62=(3 30' + 402 c 900 + 1,600 e? C² =2,5 U0 %3D C=/2500 C=50 10m shorter. jade shortcut is 172
