Work out the height of the following triangles
2 answers:
The height of first (a) triangle is 11.31 cm and the height of the second (b) triangle is 15.49 cm.
Step-by-step explanation:
The given is,
Triangle (a) and (b)
Step:1
For first (a) triangle
(Ref the attachment (a))
b = 4 cm
hyp = 12 cm
From Pythagoras theorem,
...........................(1)
Equation becomes,
= +
144 = 16 +
h =
h = 11.314 cm
Step:2
For first (b) triangle
(Ref the attachment (b))
b = 7 cm
hyp = 17 cm
From Pythagoras theorem,
...........................(1)
Equation becomes,
= +
289 = 49 +
h =
h = 15.492 cm
Result:
The height of first (a) triangle is 11.314 cm and the height of the second (b) triangle is 15.492 cm.
<u>A) </u> height = .
<u>B) </u> height = .
<u>Step-by-step explanation:</u>
Here , We need to calculate height of triangles let's do this :
A)
We draw a perpendicular from vertex to base line (8 cm ) , so length becomes 4 cm of base of triangle .
By Pythagoras Theorem we have ,

Therefore , height = .
B)
We draw a perpendicular from vertex to base line (14 cm ) , so length becomes 7 cm of base of triangle .
By Pythagoras Theorem we have ,
⇒
⇒

Answer:
13.64 cm²
Step-by-step explanation:
Area of Trapezoid :
- a and b = parallel side lengths
- h = height
Solving :
- 1/2 x (5.2 + 3.6) x 3.1
- 1/2 x 8.8 x 3.1
- 4.4 x 3.1
- 13.64 cm²
Answer:
I need to know more, can you show me a picture of the full problem?
Step-by-step explanation:
Well, if that is a comma in the number, it is already rounded. If the comma is supposed to be a decimal, the answer would be $57.
