Answer:
Step-by-step explanation:
Four triangles. Each area is bh/2.
So 8x ÷2 or 4x Multiply by 4 (small triangles) to get 16x.
48 ÷ 16 =3 so x = 3
Answer:
BC = 20
Step-by-step explanation:
AC = AB + BC
28 = x-10 + x+2
Combine like terms
28 = 2x -8
Add 8 to each side
28+8 = 2x-8+8
36 = 2x
Divide by 2
36/2 = 2x/2
18 =x
We want to find BC
BC = x+2
=18+2
=20
Answer:11
Step-by-step explanation:
4, 1, 5, 2, 3
The appropriate order is ...
(4) Open a compass so its width is more than half the length of the given segment.
(1) Without changing its width, use the compass to draw an arc above and below the given line segment from one of the segment"s endpoints.
(5) Again, without changing its width, use the compass to draw another pair of arcs from the other endpoint. One arc will be above the segment while the second arc will be below.
(2) Draw the point of intersection between the pair of arcs above the line segment and between the pair of arcs below the line segment.
(3) Use a straightedge to connect the intersection points between each pair of arcs.
Answer:
it is possible to draw a triangle with angles 90 degree, 60degree and again 60 degree
