How to calculate the angles of a triangle when you only know the value of one of them?

Help

find the angles of a triangle measuring 40 degrees on three sides

Mari

I need to know about, determine the internal angles of the indicated triangle considering the following data, it is of a scalene triangle.
A = 4x + 10 B = 7x -5 C = 15x + 45
I don’t know if it can help me

Hello, good morning, now I need to solve a problem with a triangle I need to know the value of x with two legs, one of 9 and the other 12, which is the value x

Jose Antonio

I want to know the degree of a right triangle whose two legs measure 45 and 270 cm.

William

How do I find the angles of an isosceles triangle, without further information?

Sergio

I have a triangle of these measurements Vertical measures 2000, Horizontal measures 2000 and diagonal measures 2620. What interior angles do I have?

Melany

It served me a lot, tomorrow I have a test and I did not know anything.

José

if you have a 2.5 cm high wall. determine the length of the 30 degree angle

Marta Valdez

find the value of the angles of this figure. is an isosceles triangle, data: a = 3x-20 °; b = 2x 120 °; c = x-10 °

If two sides of a triangle measure 8 and 7 can the other side measure?
a) 14
b) 17



Melany

17, I think I’m not very good at math.

if the triangle is a right triangle if possible but you would have to specify the two sides, one is the hypotenuse and both are legs and follow the Pythagorean theorem that says hypotnuse squared = leg1 squared + leg 2 squared and if one of the measures is the hypotenuse, just factor the equation to give you the result.

The answer is a. In the extreme case that the angle formed by the two sides of 8 and 7 tends to be 180 degrees, the other side cannot measure more than 8 + 7, that is 15. Therefore it is impossible for the answer to be b, 17. If the angle between the sides is less than 180 degrees, the missing side must measure less than 15.
Therefore, the answer is a, 14.

How do I calculate an angle if I know that a is 3x + 2, b is 5x and c is 2x-2.

It does not work

what am i supposed to do with this

accountant

because the sine of 90 degrees is equal to one, please also explain it to me with graph

Thank you, you saved me, I had to study for a test and one of the topics was this
Thank you
greetings from Argentina 🙂

I need to calculate the angle when I only have the lengths

I need to know how to find the amplitude of a second shekel angle in TECNICA, A: 8X-50, B: 2X + 30 and the other exercise is to find the amplitude of an angle, A: 3x-100 ° and B: X + 50 ° and it confuses me when it does NOT have anything in front of the X; I need an answer as quickly as possible …

alicia vernuccio

I need to know how I can solve this type of exercise and know if they are adjacent and find the amplitude of this angle which is like this A: 3x-100 ° and B: x + 50

alicia vernuccio

how should I find the amplitude of an angle knowing that a: 3x-100 ° and b: x + 50 ° is of the second secondary level.
