Answer: 75%
Step-by-step explanation:
15/20 = 3/4 or 75%
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.
Answer:
Height = 14.4
Step-by-step explanation:
The diagonals meet at right angles. Interesting property.
The hypotenuse is the side of the rhombus = 15 cm
One of the sides of the small triangles created by the intersection of the diagonals = 24/2 = 12
You can find the other side of the the triangle by using the Pythagorean Theorem
a^2 + b^2 = c^2
c = 15
a = 12
b = ?
12^2 + b^2 = 15^2
144 + b^2 = 225
b^2 = 225 - 144
b^2 = 81
b = 9
The area of this right angle = 9 * 12/2 = 54
There are 4 of them so 4 * 54 = 216
That's the area of the rhombus.
The h= Area / b
b = 15
h = 216/15
h = 14.4
Answer:
544 cm²
Step-by-step explanation:
hello,
to find the tsa of a rectangular prism, you use:
tsa = 2 ( lw + lh + wh )
in this case, l = 16 cm, w = 6 cm and h = 8 cm.
knowing these informations, you can proceed with using the formula.
tsa = 2 [ ( 16*6) + ( 16*8 ) + ( 6*8) ]
= 2 [ 96 + 128 + 48 ]
= 2 ( 272 )
= 544 cm²
please try to understand how i worked this out, and do let me know if you have any questions.
have a great day! thank you!
