Step-by-step explanation:
13x - 26 °+ 5x +8° = 180° ( being co- interior angle)
13x + 5x - 26 °+ 8° = 180°
18x - 18 = 180°
18x = 180°- 18°
18x = 162°
x= 162° ÷ 18
x= 9°
hope it help
Nothing is shown.
The triangle is a right triangle, 9, 12 & 15.
The triangle's area = b*h/2 = 9*12/2 = 54 sq meters each end.
------------
The 3 rectangles are 10 by 9, 12 & 15
Area of the 3 = 10*(9 + 12 + 15) = 360 sq meters
-----
Total area = 360 + 2*54
= 468 sq meters
10+18=28
17+11=28
OR
2x=28 where x=14
4x where x=7
