en un triangulo rectangulo abc rectos en b a) hallar el angulo a si c=2a b) hallar el angulo en c se a=4b+10

answer

The side

b

is

4√2

unit.

Explanation:

in right triangle

C=900,a=2,c=6c

is

the side opposite to the right angle, so it is hypotenuse,

a

and

b

are the adjacent sides of the right angle .

We know in right triangle

,a2+b2=

c2∴22+b2=62

or

b2=36−4=32∴

b=√32

or

b=4√2

unit. The side

b is 4√2

unit [Ans]

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
