Sin^2 + cos^2 = 1
so,
(x/4)^2 + (y/4)^2 = 1
we got rid of t.
Answer:
Step-by-step explanation:
1. 1/5
2. 2/5
Answer:
∠4 and ∠3
∠4 and ∠5
∠3 and ∠6
Step-by-step explanation:
A pair of angles is said to be supplementary when the 2 angles add up to give 180°.
Two right angles add up to give 180°. Also, if we have two angles on a straight line, their sum = 180°, according to the linear pair property.
Thus, since m< 3 is given as 90°, m<4 = 90°.
m<4 + m<3 = 180°.
Therefore, <4 and <3 are supplementary.
<4 and <5, <3 and <6 are both linear pairs, therefore they are also supplementary.
(7/3 *3sqrt27-2)*1/5 +sqrt(81)
answer = 10
All angles are 90 degrees, which cancels out a kite and a rhombus, leaving you with two options (rectangle or square). Using Pythagoras' theorem, you can work out that all sides are also of equal length, which means this shape is a square :)
