Answer:
$156
Step-by-step explanation:
(9600 + 5376 )/ (8 * 12) = 156
Answer:
Step-by-step explanation:
Sin(30) / X = Sin(45) / 12
use algebra to isolate X
1 / X = [ Sin(45) / 12 ] / Sin(30)
flip both sides
X = Sin(30) / [Sin(45) /12 ]
invert the denominator on the right side
X = Sin(30) * 12/ Sin(45)
Do you know what Sin(30) is off the top of your head?
and also Sin(45) ?
these are worth remembering... and you can b/c they are just
sin(0) = 0/2
sin(30) = 1 / 2
sin(45) = /2
sin(60)= / 2
sin(90) = / 2 (aka 1)
note the numerators just counts up 0, 1, 2, 3, 4 :)
Cos works the same way but counts from 90° back to 0 but exactly like sin other wise, hence why Cos and Sin both = /2 at 45 °
anyway
X = 1 / 2 * 12/ /2
X = 3
A=3
B= 2
:) nice , huh
The surface area of a triangular prism with the 3 sides slant height as 14 the base width as 8 and the base height as 6.9 is 155. 705 in²
<h3>
What is the surface area of a triangular prism?</h3>
The surface area of a triangular pyramid is the total area of all it's faces.
The properties of a triangular prism are;
- It is bounded y three lateral triangular faces meeting at one vertex.
- It has all its faces as triangles
<h3>
How to determine the surface area</h3>
Surface area = Base Area + 1÷2 (perimeter × base height)
But base area = 1÷2 (base side × height)
Base area = 1÷ 2 (8 × 14) = 0.5 × 112 = 56 in²
Perimeter = sum of all the sides = 14 + 8 + 6.9 = 28. 9 in
Base height = 6. 9in
Surface area = 56 + 1 ÷ 2 ( 28.9× 6. 9) = 56 + 0.5 × 199.41 = 56 + 99. 705 = 155. 705 in²
Surface area = 155. 705 in²
Therefore, the surface area of the triangular prism is 155. 705 in²

The value of x is 0.1810
Step-by-step explanation:
Given the equation as;
1.2÷0.375 - 0.2/6 * 4/25 ÷ 15 2/5 +0.8 = 0.016 ÷ 0.12 +0.7/x
This can be written as;
1.2÷0.375-0.4/75÷77/5+0.8=0.016÷0.12+0.7/x
Apply BODMAS style (Brackets, Of, Division,Multiplication,Addition and Subtraction) where in this case you start with division
(1.2÷0.375)-(0.4÷75) ÷ 77/5 +0.8 = (0.016÷0.12) +0.7/x
3.2 - 0.00533 ÷ 15.4 +0.8 =0.133+0.7/x
3.2-0.0003461+0.8=0.133+0.7/x---------------apply addition
3.2+0.8 -0.0003461-0.133=0.7/x
4-0.0003461-0.133=0.7/x
3.867=0.7/x
0.7/3.867=x
0.1810=x
