ED = 68
Angle GKH = 31
ABD = 224
Angle AKB = 112
Answer:

Step-by-step explanation:
The scale factor (C) is the ratio of corresponding parts of the two pyramids.
The ratio of the areas is the square of the scale factor.

Given:
A right angle triangle with angles 45, 45, 90 degrees.
Hypotenuse of the triangle =
mm
Base of the triangle = t
To find:
The value of t.
Solution:
In a right angle triangle,

Using this trigonometric ratio in the given triangle, we get




Therefore, the value of t is 7 millimetres.
