What is the missing reason in step 3?
Statements
1. mZTRV=60°, mZTRS= (4x)
2. ZTRS and ZTRV are a linear pair
3. mZTRS + MZTRV=180
4. 60-4x= 180
5. 4x = 120
6. X=30
Reasons
1. given
2. definition of linear pair
3. ?
4 substitution property of equality
5. subtraction property of equality
6. division property of equality

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

other answer is correct. i had used the radius of the radius somehow. a website:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
