Answer:

y = 7°

Step-by-step explanation:

By interior angle sum theorem of a triangle.

$51 \degree + 87 \degree + 6y = 18 \degree \\ \\ \implies 138 \degree+ 6y = 18 0\degree \\ \\ \implies 6y = 180 \degree - 138 \degree \\ \implies 6y = 42 \degree \\ \\ \implies y = \frac{42 \degree}{6} \\ \\ \huge \red{\implies y =7 \degree} \\ \\$

Ivan said that if a number end in 0 both 2 and 5 are factors of the number. Is he correct?why or why not

Nady [450]

This is true. All numbers that end in zero or five are divisible by 5, and a number that ends in zero is even, and all even numbers are divisible by two.

Given the perimeter of a rectangle and either the length or width, find the unknown measurement using the appropriate formula.

Ad libitum [116K]

The width is 18.

step by step:
1. 2 lengths are 20 which is 20+20 that's 40.
2. 76-40= 36
3. Two widths are 36 cm.
4. so do 36÷2 and that equals 18

I, so confused please help me asap!

Quadrilaterals are plane shapes that are bounded by four straight sides. Thus, the required answers to the questions are:

46. True. Other examples include kites, rhombus, etc.

47. False.

46. When a plane shape is bounded by four straight sides of equal or different lengths, it is called a quadrilateral. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual properties.

Thus the required answer to question 46 is; True. It can be observed that with respect to their individual properties, other quadrilaterals which have a pair of opposite angles to be equal include: kite, rectangle, rhombus, etc.

47. A ray segment is a given line that points or heads in a specific direction. So that the direction in which the ray moves is very important.

Thus in the given question, the required answer is; False. This is because the two given rays are moving in opposite directions. Though the two rays may have the same length of the segment.
