Answer:
see explanation
Step-by-step explanation:
This is an example of the Altitude - on - Hypotenuse theorem.
The altitude that is perpendicular to the hypotenuse of a right triangle.
The two triangles formed are similar to the given triangle and to each other.
x² = (smaller part) × (larger part) of main hypotenuse
x² = 6 + 19 = 114 ( square root both sides )
x ≈ 10.68 ( nearest hundredth )
---------------------------------------------
y² = ( smaller part) × (whole part) of main hypotenuse
y² = 6 × 25 = 150 ( square root both sides )
y ≈ 12.25 ( nearest hundredth )
--------------------------------------------
z² = ( larger part) × (whole part) of main diagonal
z² = 19 × 25 = 475 ( square root both sides )
z ≈ 21.79 ( nearest hundredth )

Answer:
∠A = 78° , ∠B = 39° and ∠C = 63°
Step-by-step explanation:
Let the measure of angle A = m°
So, according to the question
Angle B = (m/2)°
Angle C = (m - 15)°
Now by ANGLE SUM PROPERTY, the sum pf all angles of a triangle is 180°
⇒ ∠A +∠B + ∠C = 180°
or, m + (m/2) + (m -15) = 180°
Solving for m , we get 2m + (m/2) = 180 + 15
or,
or, m = 78°
Hence ∠A = 78°
∠B = (m/2) = (78/2) = 39°
and ∠C = (m -15) = 78 - 15 = 63°
