Answer:
∠A= 80°
Step-by-step explanation:
if they are supplementary then put them equal to 180
7x + 3 +7x + 23 = 180
14x + 26 = 180
14x = 154
x= 11
now plug in
7(11)+3
77+3= 80
Answer:
Ham costs: $8.249 repeating
Overall cost: 1.26 repeating
Step-by-step explanation:
$4.95 x 5/3= 8.249
2/3 + 3/5= (2 x 5) + (3 x 3)/ 3 x 5=
19/ 15 or 1 4/15
15 divided by 19= 1.26 repeating
20 x 42= 840
So the area would be 840 mm^2.
If the first bird is on top of the bird watcher and the height of the tree is the same, then we form a right triangle with right angle on the second bird.
We can solve the angle of depression by trigonometric functions. So,sin θ = 29.7 / 42.1θ = sin-1 (29.7/42.1)θ = 44.87°
Therefore, the angle of depression of the second bird and the bird watcher is 44.87°.
