Answer:

Solution given:

angle : 80°

hypotenuse:y=?

opposite=21

we have

Sin 80= $\frac{opposite} {hypotenuse}=\frac{21}{y}$

doing crisscrossed multiplication

we get

y= $\frac{21}{Sin 80°}$

<u>y=21.32</u>

Answer: 0.6

Step-by-step explanation:

The probability formula to find p(B/A) is :

P(B/A) = p(A n B) / p(B)

Which means that A is contain in B and p(A n B) is p(A)

p(A n B)= p(A)=0.6 × 0.05 = 0.03

p(B)=0.05

Therefore

P(B/A) = p(A n B) / p(B)=p(A) / p(B)

P(B/A)=0.03 / 0.05

P(B/A)=0.6

Use the information in the diagram to determine the height of the tree to the nearest foot.

Answer:

The correct option is A. The height of tree is 60 ft.

Step-by-step explanation:

From the given figure it is noticed that the building is creating a right angle triangle from a point and the tree divides the hypotenuse and base in two equal part.

According to midpoint theorem of triangle: In a triangle, if a line segment connecting the midpoints of two sides, then the line is parallel to third side. The length of line segment is half of the length of third side.

Using midpoint theorem of triangle, we can say that the length of tree is half of the building.

$Tree=\frac{1}{2}\times Building$
