Answer:

x = -7/5 and x = 9/8

Step-by-step explanation:

To solve this equation, set both parts of the "expression" equal to 0.

5x + 7 = 0

Subtract 7 from both sides.

5x = -7

Divide both sides by 5.

x = -7/5

8x - 9 = 0

Add 9 to both sides.

8x = 9

Divide both sides by 8.

x = 9/8

Answer: See the screenshot below.

Explanation:

We'll be using these trig functions

sine = opposite/hypotenuse
cosine = adjacent/hypotenuse
tangent = opposite/adjacent

The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as $\sin^{-1}$ on many calculators.

The decimal results are approximate.

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
