Answer:

b = 12mm

Step-by-step explanation:

Area of Triangle: (base x height)/2

A = 36

h = 6mm

A = (bh)/2

2A = bh

b = 2A/h

b = (2 x 36)/6

b = 12

there are 2 aircraft carriers , A&B, and carrier a is longer in length than carrier B. The total length of these 2 carriers

Alekssandra [29.7K]

Sum and difference problem.

Longer carrier = (sum+difference)/2 = (4198+10)/2 = 2104 ft
Shorter carrier = (sum-difference)/2 = (4198-10)/2 = 2094 ft.

The right triangle below has the same area as a square that mattress 6 cm on each side. Based on the dimensions in the diagram,

Anastasy [175]

the answer is d. 12 cuz a cube is the same length in each side so the width is 6 and so is the length so 6×6 =36 so that's the area of the square and 6 ×12=72 divided by 2 (since it's a triangle) is 36 so the value of x is 12

PLEASE HELP ASAP

Corey stepped back 59.71 feet to get a better view of the bird.

Explanation:

This is a right angled triangle. Let $\theta$ be the angle of elevation.

Let the adjacent side of the triangle be x for the angle $\theta$

Let the opposite side of the triangle by y for the angle $\theta$

Thus,

$\tan \theta=\frac{y}{x}$

Since, the height of the tree is 80 feet, $y=80$

To find the value of x, let us substitute $y=80$ and $\theta=68$

$x=\frac{80}{\tan 68^{\circ}}=32.32$

Since, Corey moves back a few steps to gain a better view of the bird, the angle of elevation is 41°

Now, we shall find the x for $y=80$ and $\theta=41$

$x=\frac{80}{\tan 41^{\circ}}=92.03$

To find how many feet Corey step back is to subtract the value of two adjacent sides, thus,

$x=92.03-32.32=59.71$

Thus, Corey stepped back 59.71 feet to get a better view of the bird.

The base of a triangle is twice of its hypotenuse.the sin of angle opposite to base is..?

beks73 [17]

Answer:

hey,

ur question is wrong,

base of triangle can never be longer than hypotenuse,and you have told base is twice of hypotenuse,

if hypotenuse is twice of base, then solution is give below, in picture,

and answer is 1/2
