One of the acute angles, of a right triangle is 40 degrees, what is the measure of the other acute angle?

Question

Roar.

I cant get this on my homework.

Someone help?

Answer 1

In any triangle the angles add up to 189 degrees.
In a right angle triangle, one angle is 90 degrees so the other two angles add up to 90 degrees.
therefore 40 + x = 90
x = 50
your accute angle is 50 degrees.

Answer 2

A triangle has 3 angles totaling 180 degrees. In a right triangle, one angle is 90 degrees. If one acute angle is 40 degrees, and the right angle is 90 degrees, then the other acute angle is 50 degrees.

180 - 90 - 40 = 50

Answer 3

Acute just means less than 90 degrees.
A right triangle has 1 and only 1 right degree (90).
All triangles are 180 degrees total angles - period.

So... we have a 90, a 40, and ? that make up 180.

Your last angle is 50 degrees :)

Answer 4

a right angle measures 90 degrees ,so, if one acute angle measures 40 degrees all you have to do is to subtract
40 degrees from 90 degrees to get the measurement of the other acute angle...
90-40=50 degrees
therefore the other acute angle is measured 50 degrees

Answer 5

in a triangle sum of triangles=180
in a right angle, one angle is equal to 90
other two angles is=90
x+40=90
x=90-40=50

Answer 6

we know that the sum of all angles of a triangle (any kind of triangles) is 180.
Let's call the unknown angle A.

we have:
1 angle is 40
1 angle is 90 (right triangle)
1 angle is A
sum of the angles is 180
it means

40+90+A = 180
A = 180 - 90 - 40
A = 50

Answer 7

50 degrees....
bcoz.its right triangle.so total of a triangle is 180.....
180=90+40+x(supposed)
x=180-(90+40)
x=50..
ok

Answer 8

50 degrees

180=90+40+x
90+40=130
180-130=50
50=x

Answer 9

Cos(A)= Sin(90-A) 50
