Answer:

x = -8, y = 6

Step-by-step explanation:

x + 2y = 4 ------(1)

x + y = - 2

y = - x - 2 ----------(2)

Substitute y in (1)

x + 2(- x - 2) = 4

x - 2x - 4 = 4

- x = 4 + 4

x = -8

Substitute x in (2)

y = - (- 8) - 2 = 8 - 2 = 6

APQR is inscribed in a circle with P=60, Q = 80, and R = 40. What are the measures of PQ, QR, and PR?

Sergeeva-Olga [200]

Answer:

PQ:80

QR:160

PR:120

Step-by-step explanation:

$PQ=2x$ ∠ $R$

$=2$ × $40$

= $80$

$QR=2$ × $m$ ∠ $p$

$=20$ × $80$

$=160$

$PR=2$ × $m$ ∠ $Q$

= $2$ × $60\\$

= $120$

hope it helps
