Answer:
The angles are ∠A = 108°, ∠B = 72°, ∠C =108°, ∠D = 72°
Explanation:
From the question, we have
4x+6x+5x = 180°
15x = 180°
x = 12°
∠D = 12*6 = 72°
The opposite angles are equal.
∠B = 72°
The adjacent angles are supplementary.
∠B +∠C = 180°
72°+∠C = 180°
∠C = 180°-72°
∠C =108°
∠A = 108°
Subtraction:
Subtraction serves as a representation for the act of removing items from a collection. The negative symbol stands for subtraction. For example, if four of the nine oranges that are stacked together (as in the above illustration) are then transported to a basket, the stack will now contain five oranges rather than nine. Therefore, the difference between 9 and 4 is 5, which equals 9 minus 4. In addition to applying it to natural numbers, subtraction can also be used with other kinds of numbers. The letter "-" represents subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation.
