Answer with explanation:

In Δ AB C and Δ A E D

1.≡∠AB C= ∠ A E D→→→[Each being 90°]

2.≡ B C= E D →→[Given]

3. ≡ ∠A CB = ∠ A DE →[Given]

⇒Δ AB C ≅ Δ A E D [By S AS]

≡∠ A B C and ∠ A E D, are congruent right angles.

In the Diagram given

∠AB C= ∠ A E D=90°

Remy drinks 214 cups of water every 145 hours.

Tcecarenko [31]

Answer:

1 69/145 cups

Step-by-step explanation:

We can use ratio's to solve this problem. We will put water over time

214 cups x cups

--------------- = --------------

145 hours 1 hours

Using cross products

214 *1 =145 x

Divide both sides by 125

214/145 = 145x/145

214/145 = x

145 goes into 215 1 time with 69 left over

1 69/145

P is the incenter of △JKL. Find m∠JKP. & can you please explain

dangina [55]

Answer:

m∠MKP = 35°

Step-by-step explanation:

Incenter is the intersection of angle bisectors.

∠MJP = ∠OJP, ∠MKP = ∠NKP, ∠NLP = ∠OLP

First find the value of x:

7x - 6 = 5x + 4
7x - 5x = 4 + 6
2x = 10
x = 5

Find the angle MJP:

7*5 - 6 = 29°

We know sum of interior angles of a triangle is 180°. Using this find the missing angle measure:

2*m∠MJP + 2*m∠NJP + 2*m∠MKP = 180°
m∠MJP + m∠NJP + m∠MKP = 90°
29° + 26° + m∠MKP = 90°
m∠MKP = 90° - 55°
m∠MKP = 35°

If f(x) = 2(x)^2 + 5 square root (x+2), complete the following statement (round your answer to the nearest hundredth): f(2) =

mojhsa [17]

$f(x) = 2(x)^{2} +5 \sqrt{x+2}$

$f(2) = 2(2)^{2} + 5 \sqrt{(2)+2}$

$f(2) = 2(4) + 5\sqrt{4}$

$f(2) = 8 + 5(2)$

$f(2)= 8+10$

f(2) = 18

bulgar [2K]

Answer:

z= 69

Step-by-step explanation:

79+122+90+z=360 angle sum property

360-291=69

so z=69 degree

Subtract the 45 minutes they were eating from 1:45pm since that’s when they arrived. You now have 1:00pm, you now just need to find out how long it is from 10:20 am to 1:00pm. HINT: it’s 2h 40m
