Hey there!
Formula for the area of a triangle is (1/2)bh.
Base of this triangle is 5, height is 4.
Image attached.
Plug values into the formula:
A = (1/2)(5)(4)
Simplify.
A = (1/2)(20)
A = 10
Area of the triangle is 10 units².
Hope this helps!
For a convex polygon with n sides, the sum of interior angles is (n-2)·180°. Thus, the sum of interior angles of a pentagon is (5-2)·180° = 540°.
... x° + 131° + 108° + 107° + 110° = 540°
... x° = 84° . . . . . . subtract 456° from both sides.
The value of x is 84.
X=3
(3-3)2=0
Hope this helped :)
