The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared. that is the larger triangle.
the next way to find the area i will show you is:
pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared
Answer:
by multiplying each ratio by the second number of the other ratio
Answer:
7 > -7
Step-by-step explanation:
-9 is not greater than -4
-6 is not greater than -5
I am not sure what 7 -7 means in your first option but if it is consistent, then yes, 7 is greater than -7.

Step-by-step explanation:
<u>Step 1: Define</u>
j(x) = x + 5
j(12) is x = 12
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: j(12) = 12 + 5
- Add: j(12) = 17
From the Pythagorean Theorem, we know that a^2+b^2=c^2
28^2+21^2=(5x)^2
784+441=25x^2
1225=25x^2
49=x^2
x=7
The length of the hypotenuse would be 35m.
