First, find the area of the entire traingle using the formula bh/2.
18*9/2=81 cm^2
Then subtract the area of the smaller triangle within the larger one (white triangle). It has the same base but a height of only 4.
18*4/2=36 cm^2
81-36=45
Final answer: 45 cm^2
Answer:
x>15
Step-by-step explanation:
The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180
30 + 90 = 120
180 - 120 = 60°
How easy! Just list all the factors that add up to ten.
10 + 0
9 + 1
8 + 2
7 + 3
6 + 4
5 + 5
Which ones match the requirements?
