Answer:

$\frac{4}{5}$

Step-by-step explanation:

Using the Pythagorean identity

sin²x + cos²x = 1, then

sin²x = 1 - cos²x

sinx = $\sqrt{1-cos^2x}$

note that cosΘ = $\frac{6}{10}$ = $\frac{3}{5}$

sinΘ = $\sqrt{1-(3/5)^2}$

= $\sqrt{1-\frac{9}{25} }$

= $\sqrt{\frac{16}{25} }$ = $\frac{4}{5}$

Find the values of the variables.

icang [17]

Answer:

x=8

z=132

Step-by-step explanation:

We know that 6x and 4x+16 are vertical angles, so they are equal

6x= 4x+16

Subtract 4x from each side

6x-4x = 4x-4x+16

2x =16

Divide each side by 2

2x/2 =16/2

x =8

We also know that 6x and x form a straight line

6x+z = 180

6(8) + z =180

48+z =180

Subtract 48 from each side

48-48 +z =180-48

z = 132

Angle ADG, angle BEH and angle CFI, all have two curves in their angles. Same number of curves are used to represent that their measure are equal.

So, m angle CFI = m angle ADG

So, m angle CFI = m angle ADG=> m angle CFI = 92°
