Answer:
Step-by-step explanation:
3(x-3)+x(r+4)
3x-9+xr+4x
7x+9+xr
I think x equals 54
Hope this helps
The perimeter of an equilateral triangle is just 3s as all the sides are, well, equal :) so
P=3s and we are told that P=24.6 so
3s=24.6
s=8.2 cm
It is C (2, 1) I think it is because they intersect
Answer:
The measure of the largest angle in the kite is 128 degrees
Step-by-step explanation:
we know that
The sum of the interior angles in any quadrilateral must be equal to 360 degrees
A kite is a quadrilateral
Let
A,B,C and D the measure of the interior angles
so

we have that

substitute

----> equation A
Remember that
one is four times larger than the other
so
----> equation B
substitute equation B in equation A

solve for D

Find the measure of angle C

therefore
The measure of the largest angle in the kite is 128 degrees
