Answer:

C= 55°, b= 33.8 units length , a= 23.3 units length

Step-by-step explanation:

The question is incomplete. The complete data is: a=43°, b=82° and c=28 units length

We know that the addition of the angles of a triangle is 180°, then: c = 180° - 43° - 82° = 55°

From law of sines:

sin(a)/a = sin(c)/c

sin(a)*c/sin(c) = a

sin(43°)*28/sin(55) = a

a = 23.3  units length

sin(b)/b = sin(c)/c

sin(b)*c/sin(c) = b

sin(82°)*28/sin(55) = b

b = 33.8  units length

Answer:

NO triangle exists.

Step-by-step explanation:

Given that the sides of the triangle are  a=43 ,b=82 , and c=28

To solve for unknown angles of the triangle

PLease refresh the triangle rule of inequality that the sum of any two sides is always greater than the third side

Before solving the triangle, let us check whether this is true.

a+b >c

b+c>a

But a+c is not greater than b.

Hence there cannot be any real triangle with these sides given.

Answer is no triangle exists.

Solve the equation.<br> 3 (-5y+2) = 21
soldier1979 [14.2K]

Answer:

y= -1

Step-by-step explanation:

divide both side by 3

then you'll get -5+2=7

subtract 2 from both sides to get

-5y=5

divide -5 on both sides and you'll get y= -1

(hope my explanation made sense to you)

Select all the conditions for which it is possible to construct a triangle.
Margaret [11]

The conditions for which it is possible to construct a triangle include:

  • A triangle with angles measures 60 ∘ , 80 ∘ , and 80 ∘
  • A triangle with side lengths of 4 cm, 5 cm, and 6 cm
  • A triangle with side lengths 4 cm and 5 cm and a 50 ∘ angle.

<h3>What is a Triangle?</h3>

This is defined as a three-sided polygon which has three edges and three vertices and a total internal angles of 180 degrees.

The triangle with side lengths 4 cm, 5 cm, and 15 cm can't be constructed due to the length of sides not being equal according to pythagoras theorem.
