AB is a line of symmetry of this arrow shape. A)Calculate The Perimeter of the shape. B) The Value of H
C) The area of the shape

A)58cm

B)

C)125.55square cm

Step-by-step explanation:

AB is a line is symmetry

Total length of left half part=12cm+9cm+3cm+5cm

Total length of left half part=29 cm

Length of left half part=Length of right half part

Therefore, length of right half part=29 cm

A) Perimeter of the shape=29cm+29cm=58cm

B)

Pythagoras theorem

Hypotenuse=12 cm

Base=5+3=8cm

In triangle ADC

Now, using Pythagoras  theorem

C)

Area of shape=Area of triangle+ area of rectangle

Area of shape=

Where l=9cm

breadth=3+3=6cm

h=

base=2(5)+3(2)=16cm

Area of shape=

Area of shape=125.55 square cm

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
