Step-by-step explanation:

as 145 +10 = 155°

and total angle measure of triangle is 180

so

180-155 = 25°

in option a one angle is 10

other is 25 so obviously last angle will be 145

and same is in the triangle abc

one angle is 10 other is 145 and last is 25

both hve same measures thus are same triangles.

The square prism has a base length of 2 ft. Which describes the cross section of the prism that is perpendicular to the base?

A square prism. The cross section is a rectangle with 2 12 foot sides and 2 2 foot sides.
a rectangle with two 12-ft sides and two 2-ft sides
a rectangle with two 12-ft sides and two sides that are shorter than 2 ft
a nonrectangular parallelogram with two 12-ft sides and two 2-ft sides
a nonrectangular parallelogram with two 12-ft sides and two sides that are longer than 2 ft

Answers

Answer:

A cross section perpendicular to the base would "cut" the prism through the height and width of the prism.

This would make a rectangle, with two sides the same length as the base ( 2 ft) and 2 sides the height of the prism ( 12 ft).

The answer would be:

A rectangle with two 12-ft sides and two 2-ft sides.

Answer: a rectangle with two 12-ft sides and two 2-ft sides

B. Roll a number cube and let the numbers 1 through 4 represent the number of questions you guess correctly. Run 40 trials.

C. Roll two number cubes. Let one number cube represent a correct answer and the other number cube represent an incorrect answer. Run 40 trials.

D. Roll four number cubes. Let an odd number represent a correct answer and an even number represent an incorrect answer. Run 40 trials.

Jacob has $200 to spend on STAR WARS toys. He already purchased $75 on vehicles and new action figures will cost him $8 each. How many action figures will Jacob be able to purchase?



The number that will get the VARIABLE is
. The number that represents the TOTAL is
. The number that WILL NOT get the variable is
. The equation to represent the number of action figures he can purchase is

Answers

Answer:

15 action figures

Step-by-step explanation:

Jacob had $200 to start off with. He spent $75 on vehicles, so we are going to subtract $75 from $200

200 - 75 = 125

He had $125 left. From the money he has left, he wants to purchase more toys. Action figures are $8 each. We will need to find how many action figures he can buy with the rest of his money. To do that, we will divide $125 by $8

125/8 = 15.625

He can buy 15 action figures with his remaining money. He will have remaining change.

I think the equation is:

8x + 125 = 200

8 gets the variable, 200 is the total, and 125 will not get the variable.
