Answer:
x = 2, x = -10
Step-by-step explanation:
(x+4)^2 = 36
(x+4) = 6, -6
x = 2, x = -10
Given:
The distance between the two buildings on a map = 14 cm
The scale is 1:35000.
To find:
The actual distance in km.
Solution:
The scale is 1:35000.
It means 1 cm on map = 35000 cm in actual.
Using this conversion, we get
14 cm on map =
cm in actual.
=
cm in actual.
=
cm in actual.
=
km in actual. ![[1\text{ km}=100000\text{ cm}]](https://tex.z-dn.net/?f=%5B1%5Ctext%7B%20km%7D%3D100000%5Ctext%7B%20cm%7D%5D)
Therefore, the actual distance between two buildings is 4.9 km.
Step-by-step explanation:
7, HT=
=17 cm
8, S = 1/2.AC.BC.sinC≈28,01 cm^2
9, S =1/2.SR.RT.sin R≈ 3615,7 m^2
Prove:
the area of the ABC triangles is S
sin A = BH/AB
S = 1/2 BH.AC=1/2 sinA.AB.AC=1/2*c*b*sinA
Answer:
176
Step-by-step explanation:
14x12 = 168 + 8 = 176
Step-by-step explanation:
<u>a. the area of a two-dimensional composite figure</u>
In this situation, we need to draw any necessary segments to view the figure as basic shapes, then:
- Step 1: add basic shape areas belonging to the composite shape
- Step 2: subtract basic shape areas NOT belonging to the composite shape
<u>b. the surface area of a three-dimensional composite figure</u>
As we know (3D) composite objects are made of two or more objects put together. To find the surface area of a 3D composite object, we need:
- Step 1: find the outside surface area of each object
- Step 2: add the surface areas together
