We know that the sum of the internal angles in each triangle is 180°.
Therefore we have the equation:
substitute and solve:
We have
substitute the value of x to the expression:
Answer: m∠N = 42 degrees
Answer:27
Step-by-step explanation:
A=((b1+b2)/2)h
A=((12+6)/2)(3)
A=((18)/2)3
A=27
To multiply a fraction with another fraction, we multiply the numerators the denominators:
(5/2) x (2/3) = (5 x 2) / (6 x 3) = 10/18 = 5/9
Answer:
a rectangle
Step-by-step explanation:
1. a quadrilateral has 4 sides. this has 4 sides. this is a quadrilateral
2. a parallelogram has (a) opposite sides and (b) opposite angles of equal length. here, all sides are equal so (a) can be checked off. opposite angles are also equal so (b) can be checked off
3. a rhombus has 4 sides of equal length. all 4 sides are of equal length so this is a rhombus
4. a rectangle has 4 right angles. the angles here are not perpendicular to each other. thus, right angles are not formed and this is not a rhombus
