10 x 15=150
150 is the answer
Answer:
There’s only 1 horizontal line of symmetry
Step-by-step explanation:
The value of x is 113 because the 3 angles in a triangle add up to 180° so 180 subtracted by 28° and 39° gives the value of angle x.
The value of y is 67° because x and y are supplementary angles which means they add up to 180°. So 180-113 gives y.
The value of z is 49° because if you subtract the 180° that makes up the triangle from 67 and 64, you get 49.
EXPLANATION
-A rectangle is a parallelogram. True. Every rectangle is a parallelogram.
-A square is a rhombus. True. Every square is a rhombus.
Every rhombus is a rectangle-->This is NOT always true when the rhombus has not right angles.
-True --> A square is a special type of rectangle because it possesses all the properties of a rectangle.
