Answer:
24/25
Step-by-step explanation:
In this triangle DF and FE are legs (because they form the right angle) , ED is the hypotenuse (it is the largest side, it is opposite to the right angle).
son of E is the ratio of the leg opposite to the angle E (DF) to the hypotenuse
it is 24/25
Answer:
n=13
Step-by-step explanation:
24=3(n-5)
24=3n-15
-3n=-24-15
-3n=-39
n=13
Answer:
∠a = 39°
∠b = 129°
Step-by-step explanation:
Vertical angles are congruent. An exterior angle of a triangle is equal to the sum of the remote interior angles.
<h3>Application</h3>
Angle y and angle 'a' are vertical angles, so congruent.
∠a = ∠y = 39°
The angle marked 'b' is an exterior angle to the triangle. Its remote interior angles are 'a' and the one marked 90°.
∠b = ∠a +90° = 39° +90°
∠b = 129°
