Answer:
Step-by-step explanation:
Alright so the step that comes first is adding two to both sides.
Let me show you,
Step 1
-b-2<8 Add 2 to both sides
-b<10
Then you divide the sides by -1
-b<10
b>-10
Answer:
If I am right you have to multiply 8 by 30 and than divide it by 12 the answer it will give you is x
Answer:
The values of x and y are 23.83 and 31.1.
Step-by-step explanation:
Given that,
Perpendicular = 20 units
Angle, 
We need to find the values of x and y.
Using trigonometry,

To find y use Pythagoras theorem,

So, the values of x and y are 23.83 and 31.1.
The area of the composite solid in the image given is: 399.6 m².
<h3>What is the Surface Area of a Composite Solid?</h3>
The surface are of the composite solid = area of the 3 triangular face of the top solid + area of the triangular base of the bottom solid + 3(area of rectangular face of the bottom solid).
Area of the 3 triangular face of the top solid = 3(1/2bh) = 3(1/2 × 8 × 7) = 84 m²
Area of the triangular base of the bottom solid = 1/2bh = 1/2 × 8 × 6.9 = 27.6 m²
3(area of rectangular face of the bottom solid) = 3(length × width) = 3(12 × 8) = 288 m²
Surface area of the solid = 84 + 27.6 + 288 = 399.6 m²
