Since angle 1 is opposite of angle 3, this means that angle 1 also measures 105°
It would have been better if a figure come with your question but I will just imagine how the pattern looks like.
Automatically, the area of the two parallelograms is
(14) (10) + (14)(10) = 280 square inches
The are of the three triangles assuming that they are on top of the parallelogram is
3 (1/2) (18 - 10)(7) = 84 sq. inches
The total area is
280 + 84 = 364 sq. inches
If it has a line under the 9, then it needs to be 5.49, but if it has a line under the 4 it needs to be rounded up to 5.5 since the number behind it is above 5.
You have to multiplying first, then adding on 6 over negative 3 as a fraction. The parentheses it will be multiplying.
(4)(9)+6/-3
= 34.
It will help you.
Have a great day!
