If the triangle is a right triangle, the pythagorean theorem would work
since it doesn’t, the triangle is NOT A RIGHT TRIANGLE
(see attached pic for work :))
Answer:
10.7 cm^2
Step-by-step explanation:
First find the area of the base
A = 1/2 *2*1.7
A =1.7
Then find the area of one of the sides
A = 1/2 (2*3)
A = 3
There are 3 sides and they are identical
Multiply one of the sides by 3
3*3=9
Add the sides and the base together
9+1.7
10.7 cm^2
Answer:
I believe the answer ur looking for is 3 (D)
Step-by-step explanation:
- The value of x from the figure is 8
- The perimeter of AED is 30.80
To get the value of x, we will use the similarity theorem of the triangle;
a) From the given image:
On factorizing
Since x cannot be negative, then x = 8
b) The perimeter of AED = AE + ED + AD
Given
AD = 10
ED = x = 8
AE² = AD² + ED²
AE² = 10²+8²
AE² = 100 + 64
AE² = 164
AE = √164
AE = 12.80
Perimeter of AED = 12.80 + 8 + 10
Perimeter of AED = 30.80
Hence the perimeter of AED is 30.80.
