Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
Answer:
Step-by-step explanation:
m∠JXM + m∠NXP = 180° - m∠MXN = 90°
Answer:
Step-by-step explanation:
-35/2 x (-21/5)
-7/2 x (-21/1)
-7/2 x (-21) = 147/2= 78 1/2
Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to

sq. units.
