Answer:

Angle 4 and Angle 1 are supplementary to each other.

Step-by-step explanation:

A line is 180°. Because angle 4 and angle 1 and right next to each other and they share a straight line, both of their angles should add up to 180°, making these two angles supplementary.

Given side a is 41 units, side b is 23 units and the included angle is 70°. Find the area
Lelu [443]

Answer:

886.13sq. units

Step-by-step explanation:

If the figure is a triangle

Area of the triangle =  1/2 ab sintheta

Given

a = 41 units

b = 23 units

theta = 70°

Area of the triangle  = 1/2 * 41 * 23 sin 70

Area of the triangle = 943 sin70

Area of the triangle = 943(0.9397)

Area of the triangle = 886.13

Hence the area of the triangle is 886.13sq. units

Answer:

Step-by-step explanation:

(x+2)(x-1)= x^2+2x-x-2= x^2 +x -2\\\\( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 =x^2+x-2-x^2+1=x-1\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] =-3(x-1)=-3x+3\\\\- 3 [ ( x + 2 ) ( x - 1 ) - x ^ { 2 } + 1 ] + 3 ( x - 1 ) =-3x+3+3x-3=6x\\
