Right triangles abc and dbc with right angle c are given below. If cos(a)=15,ab=12 and cd=2, find the length of bd.

dmitriy555 [2]

see the attached figure to better understand the problem

we have that

$cos(A)=\frac{1}{5} \\ AB=12\ units\\ CD=2\ units$

Step 1

Find the value of AC

we know that

in the right triangle ABC

$cos (A)=(AC/AB)\\AC=AB*cos(A)$

substitute the values in the formula

$AC=12*(1/5)\\ AC=2.4\ units$

Step 2

Find the value of BC

we know that

in the right triangle ABC

Applying the Pythagorean Theorem

$AB^{2} =AC^{2}+BC^{2}\\ BC^{2}=AB^{2} -AC^{2}$

substitute the values

$BC^{2}=12^{2} -2.4^{2}\\BC^{2}= 138.24\\ BC=11.76\ units$

Step 3

Find the value of BD

we know that

in the right triangle BCD

Applying the Pythagorean Theorem

$BD^{2} =DC^{2}+BC^{2}$

substitute the values

$BD^{2} =2^{2}+11.76^{2}$

$BD=11.93\ units$

therefore

the answer is

the length of BD is 11.93 units

Lulu has exactly enough fencing to go around her rectangular garden. She has 40 m of fencing and the garden is 8 m wide. What is

vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden $W=8\ m$

Total fencing $T=40\ m$

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is $P=2(L+W)$

$2(L+W)=40$

$L+W=20$

$L=20-8=12\ m$

thus length of fencing is $12\ m$
