4. The ratio of the measures of the three angles in a triangle is 7:8:5, what is the
34kurt

Step-by-step explanation:

let the angles be ' 7x, 8x and 5x'

as we know, the sum of all the angles of a triangle is 180 degree, so,

7x + 8x + 5x = 180

20 = 180

x = 180/2

x = 90 degrees

7x = 7 × 90 = 630 degree

8x = 8 × 90 = 720 degrees

5x = 5 × 90 = 540 degrees

therefore, 5x is the smallest degrees

Solve the equation for all values of x in simplest form (x + 3)^2 = -16
Arlecino [84]

Answer:

x = -7 or  x = 1

Step-by-step explanation:

Given expression:

    (x + 3)²  = -16

 

Problem;

   Solve for x;

Solution:

 To solve for x; we use the factorization method;

     Take -16 to the left of the equation;

      (x + 3)²  = -16

         (x + 3)² + 16 = 0

       (x+ 3)² + 4²  = 0

if    x² + y²  = (x + y)(x - y)

     So;

       (x + 3 + 4) (x + 3 - 4) = 0

       (x + 7)(x - 1) = 0

       x + 7  = 0 or x - 1 = 0

      x = -7 or  x = 1

In triangle JKL, if m
romanna [79]

Answer:

\angle L = 52\\\\\angle J = 45\\\\\angle K = 83

Step-by-step explanation:

\angle J = \angle L-7\\\\\angle K=2\angle L-21\\\\\angle L = \angle L

we know that

\angle K +\angle J + \angle L =180 by the sum of interior angles of a triangle

so we have

(\angle L -7)+(2\angle L -21)+(\angle L)=180

we can simplify

(\angle L + 2\angle L + \angle L)+(-7-21)=180\\\\4\angle L -28=180\\\\4\angle L=180+28\\\\4\angle L = 208\\\\\angle L = 52

and now we find the other angles

\angle J = \angle L -7\\\\=52-7\\\\=45

\angle K = 2\angle L -21\\\\=2(52)-21\\\\=104-21\\\\=83
