The three angles of a triangle have measures of 56°, (2x + 4)º, and xº
What are the measures of the three
angles of the triangle? (TEK 8.8D)
A. 56°, 80°, 44°
B. 56°, 90°, 34°
C. 56°, 84°, 40°
D. 56°, 60°, 64°

56°, 84°, 40°

Step-by-step explanation:

The three angles of triangles have measures of 56°, (2x + 4)º, and xº.

We need to find the measures of the three  angles of the triangle.

We know that, the sum of angles of triangle is equal to 180º. Using this property we get :

56°+ (2x + 4)º + xº =180º

Solving for x.

60 + 3x = 180

3x = 120

x = 40º

Other angle, = 2x+4

= 2(40)+4

= 80+4

= 84º

So, the measures of the three  angles of the triangle are 56°, 84°, 40°. Hence, the correct option is (c).

5x+10 is the correct one

hope this

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
