Question

Someone help me on this please!

Answer 1

Answer:formula 1/2 base x height

first step cut the triangle in half

1/2bxh?=base =24

height ?

1/2x24=12

make sense

Explanation:

Answer 2

x = 15 cm

Explanation:

All the ratio of corresponding sides should be equal

10 corresponds to x

16 corresponds to 24

12 corresponds to 18

Finding the ratio of the known pairs:

• 
  `(16)/(24)=(2)/(3)`
• 
  `(12)/(18)=(2)/(3)`

Similarly 10 is to x should be 2 is to 3. Finding x:

`(10)/(x)=(2)/(3)\\10*3=2x\\30=2x\\x=(30)/(2)\\x=15`

So x = 15.
