Hey there! :)
Area of triangles → (base × height) ÷ 2
The base and height are the 2 legs. You have to find the length of the other leg to find the area, using the Pythagorean Theorem.
a² + b² = c² → c² - a² = b²
c = 12
12² = 12 × 12 = 144
a = 10
10² = 10 × 10 = 100
144 - 100 = 44
√44 = 6.6

Area of triangles → (base × height) ÷ 2
Base: 10
Height: 6.6
6.6 × 10 = 66
66 ÷ 2 = 33
The area is 33
Hope this helps :)
Answer:
ok so it basically means reducing a mixed number to its simplest form.
Answer: B then A then C
Step-by-step explanation:
If the numerator is more than half the denominator, it is more than one half. 1/3 is the only fraction that does not meet this requirement, and is thus on the left of 1/2. 3/4 is the same thing as 6/8, which is more than 5/8 so 3/4 is on the rightmost box.
Answer:
D. 2.2m + 4.5
Step-by-step explanation:
Answer:
n=135/4z+7
Step-by-step explanation:
Let's solve for n.
4nz+7n−135=0
Step 1: Add 135 to both sides.
4nz+7n−135+135=0+135
4nz+7n=135
Step 2: Factor out variable n.
n(4z+7)=135
Step 3: Divide both sides by 4z+7.
