In ΔXYZ, ∠Y is a right angle and sin X = 12/25 Find sec X, tan X, and cos Z in fraction and in decimal form. Round to the neares

Bezzdna [24]

Answer:

In ΔXYZ

∠Y is a right angle
∠X and ∠Z are complementary angles
sin X = 12/25

-------------

sec X = 1/cos X = $1/\sqrt{1- sin^2X} = 1/\sqrt{1 - 12^2/25^2} = 1/\sqrt{481}/25 = 25/\sqrt{481}$
tan X = sin X / cos X = $12/{25 : {\sqrt{481} }/25 = 12/{\sqrt{481} }$
cos Z = sin X = 12/25

[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Identify

Angle θ = A

Opposite Leg = 27

Hypotenuse = 42

Step 2: Solve for A

Substitute [sine]: sinA = 27/42
Simplify: sinA = 9/14
Trig inverse: A = sin⁻¹(9/14)
Evaluate: A = 40.0052°
Round: A ≈ 40°

Could I get the awnser and explanation of this? Thank you!

astra-53 [7]

Answer:

equation: y = 4x-12

slope: 4

y-intercept: -12

Step-by-step explanation:

3 points across an x-axis is +1 x-axis difference and +4 y-axis away from origin, so you have to subtract 3 by 1 andsubtract y by 4. until x is 0, you get -12 on y-axis
