The value of x in the triangle with angles 80, 40 and (13x - 5) degrees is 5.
<h3>Sum of angle in a triangle</h3>
The sum of angle in a triangle is equals to 180 degrees. Recall a triangle have three sides. Therefore,
80 + 40 + 13x - 5 = 180
120 - 5 + 13x = 180
115 + 13x = 180
subtract 115 from both sides of the equation
115 - 115 + 13x = 180 - 115
13x = 65
divide both sides by 13
13x / 13 = 65 / 13
x = 5

Answer:
The answer is below
Step-by-step explanation:
A rectangle is a quadrilateral (four sides) with two pairs of equal opposite and parallel sides. All the four angles in a rectangle are equal to 90° (right angle). The diagonals of a rectangle are equal and bisect each other.
The area of a rectangle = length * breadth
a) Area = length * breadth = 8 cm * 3 cm = 24 cm²
b) Area = length * breadth = 5.2 cm * 7.7 cm = 40.04 cm²
