One acute angle of a right triangle is 55 ° and the other acute angle is______ °．

180-90-55
=90-55
=35 (degrees)
Another acute angle is 35 degrees
So the answer is: 35

In a right triangle, one of the acute angles is 35 degrees. What is the other acute angle?

55 degrees

One acute angle of a right triangle is 35 degrees. What is the other acute angle? It's about 45 degrees

It's not 45 degrees. It's 55 degrees

In a right triangle, one of the acute angles is 35 degrees and the other is______ Degree

180-90-35
=90-35
=55 (degrees)
So the answer is: 55

An equilateral triangle has an angle which must be () degree. The sum of the inner angles of a triangle is () degree. The sum of the two acute angles of a right triangle is () degree

60 180 90

The sum of the inner angles of a triangle is 180 degrees; if one acute angle in a right triangle is 30 degrees, what is the other acute angle?

60°

In a right triangle: angle c = 90 degrees, if angle a = 30 degrees, B = 15, find a, and C Using Pythagorean theorem. O very simple problem Please.

I don't know if you have studied trigonometric function, Sina = 0.5, that is to say, C = 2A has a ^ 2 + B ^ 2 = C ^ 2, we can see that B = a is three times the root, so a is 5, the root is 3, and C is 10

The length of the three sides of a right triangle is 15 cm, 20 cm and 25 cm respectively. What is the area of this right triangle

Right triangle conforms to Pythagorean theorem, 15 ^ 2 + 20 ^ 2 = 25 ^ 2,
So 10 and 20 are right angles, so the area is 10 * 20 / 2 = 100

A right triangle, the two right sides are 15 cm and 20 cm respectively, and the oblique side is 20 cm long. What is the height of the hypotenuse?

Let the height on the hypotenuse is x cm, and from the formula of triangle area:
20·150
X÷2=15×20÷2
20X=150
X=7.5
A: the height on the bevel is 7.5cm

If the two right sides of a right triangle are 20 and 15 respectively, the height on the hypotenuse is

15*20/25=12

One acute angle of a right triangle is 55 ° and the other acute angle is______ °．
