8x-41+9x+17= 180 (becuase they lie on a straight line)
17x-24=180
Move twenty four to the other side as a positive
17x=204
Divide both sides by 17
X is equal to 12
Yes it is the right answer .-.
Answer:
True, 1, 3, 5
Step-by-step explanation:
1. Angle L is sircumsribed angle, thenMJ⊥JL and MK⊥KL, so the measure of the angle L is
360°-131°-90°-90°=49° (the sum of all interior angles in the quadrilateral is 360°)
True
2. False, because m∠L=49°.
3. If the measure of arc HJ is 98°, then the measure of the central angle HMJ is 98°.
True
4. If the measure of arc HJ is 98°, then the measure of the central angle HMJ is 98° and the meausre of inscribed angle HKJ subtended on the arc HJ is half of the central angle measure and is equal to 49°.
False
5. If the measure of arc HJ is 98°, then the measure of the arc HK is
360°-131°-98°=131°
True
