(05.02) In the figure below, angle y and angle x form vertical angles. Angle x forms a straight line with the 50° angle and the 40° angle.
A straight line is shown and is marked with three angles. The first angle measures 50 degrees. The second angle measures 40 degrees. The third angle is labeled x. The line between the 40 degree angle and angle x extends below the straight line. The angle formed is labeled angle y.
Write and solve an equation to determine the measure of angle y.
☁️My Answer☁️:
y = 90°
✧My Step-by-step explanation✧:
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
A chess piece is 15 centimeters tall, and its shadow is 13 centimeters long. How far away is the top of the chess piece from the end of its shadow? Round to the nearest tenth.
Answer:
19.8 cm
Step-by-step explanation:
Using the Pythagorean theorem , the Square of the distance between the top of the piece and the Shadow Is the sum of the height of the piece. and the lenght of the shadow. basically Just build a triangle with the 3 points you are given: height of the piece, lenght of the shadow and distance between the 2. so it's sqrt(13^2+15^2) = sqrt(394) =19.8 cm

Estimate 154 divide 7
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______
7 / 154 \ 2 2

Which digit(s) make the solution of the equations the whole number? 5x-496=1.34...
Answer:
x≈ 100
Step-by-step explanation:
Given the equation
5x-496=1.34...
We are to find the value of x to the nearest whole number
Add 496 to both sides
5x-496+496 = 1.34+496
5x = 497.34
x = 497.34/5
x = 99.468
x ≈ 100
Hence the value of x to nearest whole number is 100
