I would help but I don't speak your language do u speak English not being mean
<span>1x + 2x = 15
3x = 15
3x/3 = 15/3
x = 5
Gemma = 1x, Zak = 2x therefore Gemma = 5 and Zak = 10</span>
Answer:
simplified:

and Find the integral if that's what you also wanted:

The another way to state the transformation would be 
<u>Solution:</u>
Rotation about the origin at
: 
The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to
about the origin.
So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of
.
Hence according to the representation, the expression would be
.
Answer:
95 degrees
Step-by-step explanation:
In a quadrilateral where there are two pairs of parrallel sides, the angles adjacent to each other are supplementary and add to 180 degrees. This means Angle A + Angle B = 180, Angle B + Angle C = 180, Angle C + Angle D = 180 and Angle D + Angle A = 180. If Angle A is 85 degrees then Angle B is 95 degrees. There are only two distinct angle measures within the quadrilateral. All angles for the quadrilateral are 85 or 95 degrees.
