140 × -7 = -980
5*4*6=120
4+(6+9)=19
675+9=75

Answer:
<QRP = 48.2°
Step-by-step explanation:
Given:
PR = 18 cm
QR = 12 cm
Required:
<QRP = angle R
Solution:
Reference angle = <R (<QRP)
Adjacent side length = 12 cm
Hypotenuse = 18 cm
Thus:
Cos (R) = 12/18
cos (R) = 0.6667


<QRP = 48.2° (nearest tenth)
4+4x+4x=20
4+8x=20
4=12x
3=x
