A { ( blue, green), ( blue, red) }
please mark as brainliest l need it
A rhombus is a parallelogram with four equal sides and two sets of equal angles.
If the m<1=160°, then the angle opposite (3) would also be 160°.
m<3=160°.
Becuase it is a parallelogram, the sum of the measurment of two angles that share a line would be 180 (supplementary).
m<2 and m<4 is 20°.
Answer : option B
the correct method to label a segment with endpoint E and endpoint F
The endpoints of the line are E and F
The Line starts at E and ends at F. The line will not extend after F
The line having end points are called as line segment
We represent a line segment by putting a line at the top
to label a segment with endpoint E and endpoint F, we use EF or FE and a line at the top
So answer is option B
4 because it has four sides
We are to verify the identity:
cos(α-B)-cos(α+B) = 2 sinα sinβ
Left hand side = cos(α - B)-cos(α + B)
= cosα cosβ + sinα sinB - (cosα cosB - sinα sinβ)
= cosα cosβ + sinα sinB - cosα cosB + sinα sinβ)
= sinα sinβ + sinα sinβ
= 2 sinα sinβ
= Right Hand side
