2a+3r+1.5p=29.75 (1) a+r+p=13.50 (2)
a+3r+4p=29.00 (3)

Eliminate a by using equation (2) by -1 and adding ut to equation (3).

What is the resulting equation?

A) 4r+5p=42.50
B) 2r+3p=15.50
C) 2r+3p=42.50

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
