Find the value of d.
Ket [755]
First find the value or (DEA)
For this you will have to use the Pythagorean theory,
{a}^{2} + {b}^{2} = {c}^{2}
C is mainly the hypotenuse,
Meaning you either want to find A or B,

Since the hypotenuse has two segments, both values are 10, then just add them together making it 20,

Then 16 will be A or B, in this case it will be A,

To find a you must first move A to the other side by doing the opposite,
{b}^{2} = {c}^{2} - {a}^{2}
Now plug in the values,
{b}^{2} = {20}^{2} - {16}^{2}
{b}^{2} = 400 - 256
{b}^{2} = 144
Now just find the square root of both factors,
\sqrt{ {b}^{2} } = \sqrt{12}
The value of (DEA) is,
b = 12
Now we want to find (d)
Since 12 is the value of the base, then divide it 2 to find (DE), after just repeat the whole process but with the value of hypotenuse 10 instead of 20 since we want to find the smaller triangle,
{a}^{2} = {c}^{2} - {b}^{2}
Now plug in the value
{a}^{2} = {10}^{2} - {6}^{2}
{a}^{2} = 100 - 36
{a}^{2} = 64
Now find the square root of both factors,
\sqrt{ {a}^{2} } = \sqrt{64}
a = 8

The value of (d) is (8)

Solve the expression x + 3 = 7
Daniel [21]

Answer:

x=4

Step-by-step explanation:

think of the equation like this: you have to do the inverse(opposite) operations so for adding you would subtract it. So for the adding 3 you would subtract it from both sides of the equation and get X=4
