Answer:
12x9= 124
Step-by-step explanation:
if you multply it right
I believe the second one, double check
Well, it is a good and interesting question
Such areas could be calculated in a single shoot and also by dividing the whole shape into other shapes and the total area would be the sum of these areas
I prefer the way of a single shoot ...
The figure represents a trapezoid:
its lower base = 21 units
its upper base = 12 units
the normal height between them = 8 units
NOW
The area of a trapezoid = [(sum of bases' lengths) ÷ 2] * height
= [(12 + 21) ÷ 2] * 8 = 132 sq units
Hope that helps
Answer:
FG = 19
Step-by-step explanation:
The two sides of the triangle are equal since JG is a perpendicular bisector
FG = HG
5x-6 = 3x+4
Subtract 3x from each side
5x-3x -6 = 3x+4-3x
2x-6 =4
Add 6 to each side
2x-6+6 =4+6
2x = 10
Divide by 2
2x/2 = 10/2
x =5
We want to find FG
FG = 5x-6
FG = 5(5)-6
= 25-6
= 19

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Set up Equation</u>
x + (x + 65) + 25 = 180
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 2x + 90 = 180
- Isolate <em>x</em> term: 2x = 90
- Isolate <em>x</em>: x = 45
