Question

the measurement of two acute angle of right angles triangle is y and 2y. then find the measure of these two angles.​

Answer 1

Answer:

y = 30°

Step-by-step explanation:

Given

one acute angle= y

another acute angle=2y

Given that two acute angles are of right angle

So,

y+2y=90°

3y=90°

y=90°/3

y=30°

Answer 2

Answer:

$y=30^0$ and $2y=60^0$ are the two angles.

Step-by-step explanation:

Given that a right-angled triangle's two acute angles are  $y$ and $2y$

Since its a right-angled triangle, the third angle is a right angle i.e. $90^0$

We know that the sum of the angles in a triangle is $180^0$

That is,

$y+3y+90^0=180^0$

$3y=180^0-90^0\\\\y=\frac{90}{3}\\\\ y=30^0$

Hence, $y=30^0$ and $2y=60^0$ are the two angles.

Right-angled triangle:

• A right triangle is a triangle in which one of the angles is at a right angle or two of the sides are perpendicular.
• More formally know as an orthogonal triangle.
