Right triangle G H I with right angle at H. G H is 77 centimeters. G I is 85 centimeters. H I is 36 centimeters. Right triangle J K L with right angle at K. J K is 60 centimeters. J L is 68 centimeters. K L is 32 centimeters. Right triangle M N O with right angle at N. M N is 35 centimeters. M O is 37 centimeters. N O is 12 centimeters. Right triangle D E F with right angle at E. D E is 22. 5 centimeters. D F is 25. 5 centimeters. E F is 12 centimeters

Answer 1

The triangles could not be similar to triangles ABC 15 cm, 17 cm, and 8cm will be option C and D because the other angle does not match.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The dimension of the triangle ABC is 15 cm, 17 cm, and 8 cm. And the triangle is a right-angle triangle. Then the other two angles are given as,

sin θ = 15 / 17

sin θ = 0.88235

θ = 61.93°

∅ = 90° - 61.93°

∅ = 28.07°

Let's check all the options. Then we have

A. 22.5 cm / 25.5 cm, then the sine of the angle is given as,

sin x = 22.5 / 25.5

x = 61.93°

B. 60 cm / 68 cm, then the sine of an angle is given as,

sin x = 60/68

x = 61.93°

C. 77 cm / 85 cm, then the sine of an angle is given as,

sin x = 77/85

x = 64.94°

D. 35 cm / 37 cm, then the sine of an angle is given as,

sin x = 35/37

x = 71.08°

The triangles could not be similar to triangles ABC 15 cm, 17 cm, and 8cm will be option C and D because the other angle does not match.

Correct me if im wrong :)
