The expression sin 57° is equal to

ValentinkaMS [17]

Answer:

$cos(33^{\circ})$

Step-by-step explanation:

Given

$sin(57^{\circ})$

Required

Determine an equivalent expression

In trigonometry:

$sin(\theta)= cos(90^{\circ} - \theta)$

In $sin(57^{\circ})$

$\theta=57^{\circ}$

Substitute $57^{\circ}$ for $\theta$

in $sin(\theta)= cos(90^{\circ} - \theta)$

$sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})$

$sin(57^{\circ})= cos(33^{\circ})$

Hence, the equivalent expression is: $cos(33^{\circ})$

kotegsom [21]

Answer:

Jack ran 38 km and Ted ran 43 km.

Step-by-step explanation:

Let Jack’s displacement be $x$

$x + (x+5) = 81$

$2x + 5 = 81\\2x = 76$

$x = 38 km$

$x+5 = 38 + 5\\x+5 = 43km\\$

Could anyone pls help me with this geometry question? :)<br><br> thank you soo much for the help :)

Vsevolod [243]

Answer: 103 degrees

Step-by-step explanation:

**point M is the center point of triangle ABC since it intersects both bisectors of Angle A and B.

Angle AMB=Angle M

A/2=

58/2=29 ==> Angle bisector divide an angle by half.

B/2=

96/2=48

29+48+M=180 ==> AMB is a new triangle formed inside triangle ABC.

77+M=180

M=103 degrees

AMB=103 degrees
