Answer:

35°

Step-by-step explanation:

Let's call the third angle x

The sum of interior angles in a triangle is equal to 180°

So the sum of 33° + 112° + x = 180°

145° + x = 180°

x = 180 - 145

x = 35°

Suma a 3 numere naturale este 163. Scazand al treilea numar din suma primelor doua numere, obtinem 67. Scazand primul numar din
Vika [28.1K]

Answer: x=63, y=52, z=48

Step-by-step explanation:

The complete question in english is:

The sum of 3 natural numbers is 163. By subtracting the third number from the sum of the first two numbers, we get 67. By subtracting the first number from the sum of the last 2 numbers, we get 37. Determine the 3 numbers

According to this we have a system with three equations and three unknown values:

x+y+z=163 (1)

x+y-z=67 (2)

-x+y+z=37 (3)

Let's begin by isolating x from (1):

x=163-y-z (4)

And substitute (4) in (2):

163-y-z+y-z=67 (5)

Isolating z:

z=48 (6) We have found the first number

Substituting (6) in (1):

x+y+48=163 (7)

Adding (7) to (3):

\left \{ {{x+y+48=163} \atop {-x+y+z=37}} \right

We have the following:

2y+96=200

Isolating y:

y=52 (8) This is the second number

Substituting (6) and (8) in (1):

x+52+48=163 (9)

Isolating x:

x=63 (10) This is the third number

Answer:

19 degrees

Step-by-step explanation:

From the question given

The interior angles are x+12 and x - 3

Exterior angle is <IJK = 5x-6

Using the rule that states that the sum of interior angle of a triangle is equal to the exterior

<JHI + <HIJ = <IJK

x+12 + x-3 = 5x - 6

2x+9 = 5x -6

2x - 5x = -6-9

-3x = -15

x = -15/-3

x = 5

Get <IJK

Recall that <IJK = 5x - 6

<IJK = 5(5) - 6

<IJK = 25-6

<IJK = 19 degrees

Hence the measure of <IJK is 19 degrees
