Answer:

AREA of triangle=-7

Step-by-step explanation:

x1=4,x2=5,x3=11;y1=3,y2=4,y3=2

area of triangle=1/2[x1(y3-y2)+x2(y2-y1)+x3(y1-y2)]

=1/2[4(2-4)+5(4-3)+11(3-4)]

=1/2[4(-2)+5(1)+11(-1)]

=1/2[-8+5-11]

=1/2[-19+5]

=1/2[-14]

=-7

A, B and C lie on a straight line.Given that angle y=115° and angle z=96°, work out x

Answer»

ANSWER:

X = 19°

Explanation:

y=180°-115° = 65°

x+65°+z = 180° [ Sum of angles in a TRIANGLE is 180° ]

x+65°+96°=18°

x=19°
