At the school carnival, the sixth graders are making directional arrows, as shown below. A polygon shaped like an arrow is shown. The total height of the arrow head and the arrow tail is 7 inches. The base of the arrow tail is 4 inches. The width of the arrow is 6 inches, and the height of the tail of the arrow is 5 inches.

Each arrow is to be painted red. How much area needs to be painted for 1 arrow?

To make it easier heres the picture!:

32 Inches

Step-by-step explanation:

First, split arrow into triangle and rectangle

Rectangle:

Area=5x4

       =20

Triangle:

Area=6x2

       =12

Add both shapes areas together

to find total

Total=32 Inches

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
