Select all the true statements. Line A G passes through points C and E. segments are drawn to create two triangles above A G, using the line as their bottom sides, and one triangle below A G using the line for its top side. The triangles above A G are A B C and E F G. The triangle below it is C D E. A C is congruent to C E and E G. A B is congruent to D E and E F. C D is 10 units and B C is 12 units. Angle C A B is 50 degrees and angle D C E is left parenthesis 5 x minus 10 right parenthesis degrees.
A. m∠CED = m∠CAB
B. m∠CAB > m∠CED
C. BC > FG
D. FG = 10
E. EG = 12

step-by-step explanation:

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

you save $70

discount would be 35% off
