Step-by-step explanation:
The answer is 24 I think.
using the formula for finding the area of a triangle, which is....
Area= b times height divided by 1/2 or 2
First step is to multiply 6 which is the base by the height 8 to get 48. Then 48 divided by 2 is 24.
Step-by-step explanation:
the area of the triangle can be find by using the heron's formula...
that is:
√s-a×s-b×s-c
So,
a=8cm,b=6cm,c=10cm
Semi perimeter= 8+6+10/2=24/2=12
√12(12-8)(12-6)(12-10)
=√12×4×6×2
=√ 2×2×3×2×2×2×3×2
= √2×2×2×3
= 12 cm...

An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 28 feet up. The ladder makes an angle of 64 ∘with the ground. Find the length of the ladder. Round your answer to the nearest tenth of a foot if necessary.
Answer:
31.2 ft
Step-by-step explanation:
sin = opp/hyp
sin64 = 28/hyp
hyp = 28/sin64
use calculator
hyp = 31.15285433330529
Rounded
31.2 ft
The length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.
The ladder, the distance from the wall to the base of the ladder and the distance from the ground to the electric box forms a right angled triangle.
Trigonometric ratios shows the relationship between the sides and angles of a right angled triangle.
Let x represent the length of the ladder, hence:
sin(64) = 28 feet/x
x = 28 feet / sin(64)
x = 31.2 feet
Hence the length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.

A car company sells a scale model to of the size of one of its cars.
Complete the following table.
Scale Model
Real Car

Area of windscreen (cm)
135
V25
[3]
3
Volume of storage space (cm)
408000
Answer:
[tex]w = 13500[/tex] --- real windscreen
[tex]v = 408[/tex] --- scale volume
Step-by-step explanation:
Given
[tex]k = \frac{1}{10}[/tex] --- scale factor
See attachment
Required
Complete the table
To get the windscreen (w) of the real car, we do the following computation
[tex]w = \frac{w_{scale}}{k^2}[/tex]
This gives:
[tex]w = \frac{135}{(1/10)^2}[/tex]
[tex]w = \frac{135}{1/100}[/tex]
[tex]w = 13500[/tex]
Next, the volume (v) of the scale mode
We make use of the following computation
[tex]v = v_{real} * k^3[/tex]
So, we have:
[tex]v = 408000 * (1/10)^3[/tex]
[tex]v = 408000 * 1/1000[/tex]
[tex]v = 408[/tex]

A regular hexagon abcdef is shown. Work out the size of angle x
Please help
Answer:
30
Step-by-step explanation:
cause the angles in a hexagon should add up to 720degrees(area) which means each angle in a hexagon is 120.
Angles in a triangle add up to 180
we know that A is 120 and the angles of F and B are equal (this is an assumption) so 180-120=60 then 60/2 (because we have 2 angles) 30
So X=30
(sorry if the answer is incorrect)
Answer:
30
(6-2)(180)/6
=120
∆FAB=180°
180-120=60
x=60/2
=30

SURFACE AREA PLEASE HELP
Answer:
486 yd^2
Step-by-step explanation:
Surface area is just finding the area of each face in a figure and adding it all up.
For the surface area of a cube, use this formula:
(a^2) 6
(a is the side length) a^2 is the area of one face of a cube, then multiply it by 6 since there are 6 faces on a cube.
Use formula with given dimensions:
(9^2) 6 = 486
Surface area is measured in square yards
(yards in this case)
Therefore, the surface area of the cube is 486 yd^2
