The angles in a triangle are in the ratio 1:2:3. Show that the triangle is a right - angled triangle.
Alja [10]

Answer:

Angles in a triangles add up to 180°

Respectively 1 : 2 : 3 is going to be 1 x , 2 x and 3 x so,

1 x + 2 x + 3 x = 180°

⇒ Simplify

6 x = 180°

⇒ Divide by 6 on both sides to isolate x

x = 30°

Since the ratio was 1 x : 2 x : 3 x and x is 30°,

30 : 60 : 90

And since there is a 90° angle, it is a right - angled triangle

I need help with these ASAP thanks
Nataly_w [17]

Answer:

a. y=\frac{2x}{x-5}

b. y=\frac{2-4x}{x-3}

Step-by-step explanation:

change switch x and y and then solve for y.

a. x=\frac{5y}{y-2}

x(y-2)=5y

xy-2x=5y

xy-5y=2x

y(x-5)=2x

y=\frac{2x}{x-5}

same for b.

b. x=\frac{3y+2}{y+4}

x(y+4)=3y+2

xy+4x=3y+2

xy-3y=2-4x

y(x-3)=2-4x

y=\frac{2-4x}{x-3}
