Steps in constructing a circumscribed circle on a triangle using a just a compass and a straight edge.
1) construct a perpendicular bisector of one side of ΔRST.
2) construct another perpendicular bisector of another side of ΔRST
3) the point where the two bisectors intersect will be the center of the circle.
4) place the compass on the center point, adjust its length to ensure that any corner of the triangle will be reached and draw the circumscribed circle.

Answer:
8.8 tsp
Step-by-step explanation:
4/5=x/11
cross multiply
44=5x
44/5=x
x=8.8
Answer:
x + 3
Step-by-step explanation:
Given
(8x - 6) - (7x - 9)
Distribute the first parenthesis by 1 and the second by - 1
= 8x - 6 - 7x + 9 ← collect like terms
= x + 3
Answer:
B. 74
Step-by-step explanation:
The surface area is just the area of the two triangular bases plus the area of the three rectangular sides.
Area of a triangle = (1/2)bh, where b is the base and h is the height. Here, b = 4 and h = 3.5. So: (1/2) * 4 * 3.5 = 7. However, we have two triangles, so we multiply 7 by 2: 7 * 2 = 14.
Area of a rectangle = bh, where b is the base and h is the height. Here, b = 5 and h = 4. So: 5 * 4 = 20. However, there are three rectangles, so we multiply 20 by 3: 20 * 3 = 60.
Now, we just add these together: 14 + 60 = 74.
Thus, the answer is B.
Hope this helps!
