Question

One angle of a right triangle measures 80 degrees what is the measure of the other acute angle

Answer 1

Answer : The measure of the other acute angle is, $10^o$

Step-by-step explanation :

Right angle triangle : It is a type of triangle in which the one angle is $90^o$.

As we know that the sum of interior angles of a triangle is equal to $180^o$.

$\angle A+\angle B+\angle C=180^o$

Given:

$\angle A=80^o$

$\angle B=90^o$

Now put all the given value of angle in the above expression, we get:

$\angle A+\angle B+\angle C=180^o$

$80^o+90^o+\angle C=180^o$

$\angle C+170^o=180^o$

$\angle C=180^o-170^o$

$\angle C=10^o$

Thus, the measure of the other acute angle is, $10^o$

Answer 2

$90 + 80 + x = 180$
$x = 10$
