Answer:
16 cm2
Step-by-step explanation:
By equa tion of area of triangle: S = 1/2 * height * base
Triangle B: 32 = 1/2 * 8 * x --> x = 8 (cm)
The base of triangle A is half of the base of triangle B so it is 4 cm.
The area of triangle A = 1/2 * 8 * 4 = 16 (cm2)
Answer:
Currently temperature = 35°F
Rate of descend = 4°F
We have to reach = -1°F
Temperature to get cooled down = |-1 + 35| (The two lines mean absolute value)
=> 36°F
Hours = Total temperature to get cooled / Rate
=> 36 / 4
=> 9 hours
Equation = 4x = |1 + 35|
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
You would add 13+19=32
then add 32+7 which equals 39 :P
