Answer:
Area = B x H + L (sum of sides of triangle)
= 9 x 12 + 10 (12 + 15 + 9)
= 108 + 360
=
Either your options are wrong or question is to find lateral surface.
Lateral Surface area = ( a + b + c) x H , where a, b , c are sides of the triangle.
Lateral Surface Area = (12 + 15 + 9) x 10
=
Answer:
x=65 degrees
Step-by-step explanation:
There is a theorem that states: The sum of an exterior angle of a triangle is equal to the sum of the nonadjacent interior angles.
Therefore:
2x-15= 50 + x
x=65
The answer is 12:40 or 3:10
8(2:5)= 16:40
4(3:10)=12:40
Add them and get 28:40 and minus 40-28 and get 12:40
To double check multiply the ratios in smaller numbers but have the same total ratio. Hoped this works!!
Answer:
A
Step-by-step explanation:
- 1/5 of 5x is -1 or just -x and -1/5 of 20 is -4. Then the other one is-1/4 of 4 is -x and -1/4 of -28 is 7. Now combine like terms so -x + -x is -2x and 7+ -4 or 7-4 is 3
