Answer:

21

Step-by-step explanation:

Law of cosines

\tt c=\sqrt{AC^2+BC^2-2\cdot AC \cdot BC\cdot\cos C}\\\\{} \ \ =\sqrt{10^2+17^2-2\cdot10\cdot17\cdot(-0.152985)}\\\\{} \ \ \approx\sqrt{100 +289+52} \approx\sqrt{441} \approx21 \ units

Answer:

c = 21

Step-by-step explanation:

You are given the lengths of two sides and the measure of the included angle. You must use the Law of Cosines.

c^2 = a^2 + b^2 - 2ab\cos C

c^2 = 17^2 + 10^2 - 2(17)(10)\cos 98.8^\circ

c = 21.0004

c = 21

Given: KLMN is a rectangle m∠NKM = 58° MP −∠ bisector of ∠KML Find: m∠KPM
PilotLPTM [1.2K]
According to the rule of angles and parallel lines, we can say that ∠NKM and ∠KML are equal because they are alternate angles. Since MP is a bisector, ∠KMP = ∠LMP = 1/2∠NKM = 29°. We know that ∠MKL = 90°-∠NKM = 32°. According to the sum of all angles of the triangle, ∠KPM = 180-(32+29) = 119°.

The interior angles formed by the sides of a hexagon have measures that sum to 720°.
ira [324]

Answer:

F=140

Step-by-step explanation:

Remember that all angles will be able to add to 720 so you should get something like this:

130+120+110+x-20+x-60+x-40=720      

Then solve for x to do this:

130+120+110+x-20+x-60+x-40=720

360-120+3x=720

3x+240=720

3x=480

x=480/3

x=160

With x=160, you can plug in to solve and find that F=140
