Answer 1

Answer:

• 16) 102°
• 18) 75°

Step-by-step explanation:

16)

∠QPR = 1/2(QR + SV)

• 26x - 2 = 1/2(131 + 18x + 1)
• 26x - 2 = 66 + 9x
• 26x - 9x = 66 + 2
• 17x = 68
• x = 68/17
• x = 4

∠QPR = 26*4 - 2 = 102°

18)

mBC = ?

∠BAC = 1/2(mBC + mFD)

• 8x + 6 = 1/2(8x + 11 + 9x - 7)
• 8x + 6 = 1/2(17x + 4)
• 16x + 12 = 17x + 4
• 17x - 16x = 12 - 4
• x = 8

mBC = 8*8 + 11 = 75°
