Complete question is attached.
Answer:
a) ED = 6.5 cm
b) BE = 14.4 cm
Step-by-step explanation:
From the triangle, we are given the following dimensions:
AB = 20 cm
BC = 5 cm
CD = 18 cm
AE = 26 cm
We are asked to find length of sides ED and BE.
a) Find length of ED.
From the triangle Let's use the equation:
Cross multiplying, we have:
AB * ED = AE * BC
From this equation, let's make ED subject of the formula.
Let's substitute figures,
Therefore, length of ED is 6.5 cm.
b) To find length of BE, let's use the equation:
Cross multiplying, we have:
AB * CD = AC * BE
Let's make BE subject of the formula,
From the triangle, length AC = AB + BC.
AC = 20 + 5 = 25
Substituting figures, we have:
Therefore, length Of BE is 14.4cm
Answer:
It is equal to 0.
Step-by-step explanation:
I can simplify it as follows:
sinα sin(90 - α) - cos(90 - α)(cosα)
Now sin(90 -α) = cosα and cos(90 - α) = sinα) ( for α < 90)
So the expression becomes:
sinαcosα - sinαcosα
= 0 .
