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

The circumscribed angle L has a measure of 49°.

If the measure of arc HJ is 98°, the measure of angle HMJ is 98°.

If the measure of arc HJ is 98°, the measure of arc HK is 131°.

I really don't get this type of math so can someone please help me with this thank you

solmaris [256]

The area for a trapezoid is A=1/2(b*1+b*2)h
Your base is your two parallel sides, and your parallel sides in this case is 5cm and 11cm, so that means your bases are 5&11. Your height is 4.
A=1/2(5+11)4
In order to do this you need to do the distributive property first.
1/2 x 5 = 2 1/2
1/2 x 11 = 5 1/2
Then next you need to do:
2 1/2 + 5 1/2 = 8
The last step is to do:
8 x 4 = 32
SO THE ANSWER IS 32.

Answer:

I know this is a bit late but it is 6 and 12

Step-by-step explanation:

if we use the formula b1 + b2 x h/ 2, u would do inverse operations. you multiply 2 on each side so that 72 would equal b1+b2xh and divide height on each side to get 18 is b1 + b2. if b1 is 2 times, it would be 2x + x is 3x and divide 3 on each side would give you 6 for x. If 6 is x, one side would be 6 and the other would be 12

HELP Select the correct answer.<br> What is the solution of this linear system?

deff fn [24]

The solution for the given linear equation is ( 14, 8, 10 ), that is mentioned in option C.

Step-by-step explanation:

The give linear equations,

$p+q+r = 32$ ............................(1)

$p-r = 4$ .............................(2)

$2p+q=36$ ............................(3)

Step:1

Check for Option A,

A ( 16, 8, 8 ) - ( p, q, r )

Equation (1) becomes,

16 + 8 + 8 = 32

32 = 32

Equation (2) becomes.

16 - 8 = 4

8 ≠ 4

Equation (3) becomes,

2(16) + 8 = 36

40 ≠ 36

Check for Option B,

B ( 14, 10, 8 ) - ( p, q, r )

Equation (1) becomes,

14 + 10 + 8 = 32

32 = 32

Equation (2) becomes.

14 - 8 = 4

6 ≠ 4

Equation (3) becomes,

2(14) + 10 = 36

38 ≠ 36

Check for Option C,

C ( 14, 8, 10 ) - ( p, q, r )

Equation (1) becomes,

14 + 8 + 10 = 32

32 = 32

Equation (2) becomes.

14 - 10 = 4

4 = 4

Equation (3) becomes,

2(14) + 8 = 36

36 = 36

Check for Option D,

D ( 10, 12, 10 ) - ( p, q, r )

Equation (1) becomes,

10 + 12 + 10 = 32

32 = 32

Equation (2) becomes.

10 - 10 = 4

0 ≠ 4

Equation (3) becomes,

2(10) + 12 = 36

32 = 36

Check for Option E,

E ( 10, 15, 10 ) - ( p, q, r )

Equation (1) becomes,

10 + 15 + 10 = 32

35 ≠ 32

Equation (2) becomes.

10 - 10 = 4

0 ≠ 4

Equation (3) becomes,

2(10) + 15 = 36

35 ≠ 36

Result:

The solution for the given linear equation is ( 14, 8, 10 ), that is mentioned in option C.
