<h2>angle in triangle</h2>

because the triangle above is an isosceles triangle, then both angles are of the same value.

and one thing you should know, the angle above shows the straight angle.

so the sum of all angles is 180°

can be written like this :

(5x+13)°+(3x+7)°=180°

5x + 13 + 3x + 7 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 20

(*the third choice is correct)

Answer= 20

The line is equal to 180 degrees (1/2 of 360 degrees) so you combine 5x+13 and 3x+7 and set it equal to 180 in order to find X which ends up being 20.

The sum of a number xx and 4 equals 12. an equation that represents this sentence is

lora16 [44]

X + 4 = 12

This is because the question gives you everything you require for this sentence to be formed. 12 is the final answer. 4 is added on and $x$ is basically the number that is to be found.
