Divide top and bottom by 2= 7/1
Multiply top and bottom by 3. 21/3
Multiply top and bottom by 4 = 28/4
Answer:
A = 4 units ^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the length of the base and h is the height
A = 1/2 ( 4) (2)
A = 4 units ^2
8/12 is equal to 2/3 because 2 x 4 and 3 x 4 equals 8/12
Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1
3 units
you have to use the distance formula to find the answer. it comes out as u have to square nine and nine squared is 3
