Since the triangles are similar, we can use ratios to find what x equals.
Ratios:
3x+8/4 = 25/5
The easiest way to solve ratios, in my opinion is to cross multiply.
3x+8*5 = 4*25. Simplify to get 15x + 40 = 100.
Subtract 40 on both sides. 15x = 60.
Divide 15 on both sides. x = 4.
Answer:
6 units
Step-by-step explanation:
A translation is a rigid body motion, meaning that it is a type of transformation that doesn't change the length of any sides, or it is the same as the original image. Since A'C' corresponds to AC, it must be 6 units as AC is 6 units.
Answer:
46.7°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationships between sides and angles in a right triangle.
<h3>Sine</h3>
Here, the side lengths given are the hypotenuse (11) and the side opposite the angle (8). The mnemonic reminds you the relation involving those sides is ...
Sin = Opposite/Hypotenuse
Applying this to the given triangle, you have ...
sin(x) = 8/11
<h3>Angle</h3>
The angle is found using the inverse sine function. This may be called the sin⁻¹ function on your calculator. It is also referred to as the arcsine function.
x = arcsin(8/11) ≈ 46.658°
x ≈ 46.7°
