Answer:
8.8
Because you can devide 66 by 7.5
Step-by-step explanation:
8)
3x + 2 = 4x - 3
4x - 3x = 2 +3
x = 5
2y +7 = 4y - 9
4y - 2y = 7+9
2y = 16
y = 2
9)
2x - 2 = x + 2
2x - x = 2+2
x =4
5y - 8 = y+24
5y - y = 24 +8
4y = 32
y = 8
3and5 are both divisible by 15
7x + 5x = 180
12x = 180
x = 15
Therefore, the 2 angles equal (7*15) and (5*15) which equals
105 degrees and 75 degrees
The required polygon whose area is to be calculated is attached below :
Answer:
16 unit²
Step-by-step explanation:
From the graph, the polygon is a triangle with height of 8 units and base of 4 units ;
Area of a triangle is given as :
Area = 1/2 * base * height
Area = 1/2 * 4 * 8
Area = 2 * 8
Area = 16 unit²
