Find the perimeter of a rectangle whose length is 150 m and the diagonal is 170 m
zzz [600]

Answer:

460 m

Step-by-step explanation:

Use right triangle PSR with right angle S to find the length of PS.

The Pythagorean theorem can be used for this.

a^2 + b^2 = c^2

(PS)^2 + (SR)^2 = (PR)^2

(PS)^2 + (150 m)^2 = (170 m)^2

(PS)^2 = 22500 m^2 = 28900 m^2

(PS)^2 = 6400 m^2

PS = 80 m

PS = 80 m; SR = 150 m

perimeter = 2(length + width)

perimeter = 2(150 m + 80 m)

perimeter = 2(230 m)

perimeter = 460 m

Which sequence is modeled by the graph below? coordinate plane showing the points 1, 2; 2, 2; 3, 2; 4, 2
prisoha [69]

We will start with plotting the x coordinates and y coordinates on the graph

The points 1, 2; 2, 2; 3, 2; 4, 2  have been plotted on the graph which has been attached as an image to the solution.

We can see that the value of y is staying constant (2) for all values of x.

Hence, the points represent the equation y = 2.

Answer:

x= 45

Step-by-step explanation:

angle EOB = 90 degrees so angle EOA must also be 90 degrees. Divide 90 by 2 = 45. You can figure out the rest from now on.
