Answer:
See explanation
Step-by-step explanation:
Given
--- scale factor
See attachment for triangles
Solving (a): The relationship between the angles of both triangles
The sine of an angle is:
By comparing the above to
Using Pythagoras theorem:
So, we have:
Collect like terms
Take square roots
--- approximated
For angle X, we have:
So, the relationship between both triangles are:
Solving (b): How to find CB and AB
In (a), we have:
For angle X, we have:
This implies that:
is dilated by scale factor 2 to give
So, CB and AB of are:
Answer:
33% or 33.3%
Step-by-step explanation:
You divide 1 into 3 you will get 33 repeating .Then you move the decimal two spots to the right
Answer:
56.8 m²
Step-by-step explanation:
This shape is clearly a trapezium / trapezoid. So :
Area of a trapezium is given by the formula :
Substitute values given in diagram :
a = 4.2
b = 10
h = 8
7.1 × 8 = 56.8
Units will be m² as this is area
Giving us our final answer of 56.8 m²
This is probably wrong but 11w (like saying 11 times w)
