Answer:

∠MLP = 72° , ∠LJK = 22° , ∠JKL = 72° , ∠KLJ = 86°

Step-by-step explanation:

Here, given In ΔJLK and ΔMLP

Here, JK II ML, LM = MP

∠JLM = 22° and ∠LMP = 36°

Now, As angles opposite to equal sides are equal.

⇒ ∠MLP = ∠MPL = x°

Now, in ΔMLP

By ANGLE SUM PROPERTY: ∠MLP + ∠MPL + ∠LMP = 180°

⇒ x° + x° + 36° = 180°

⇒ 2 x = 180 - 36 = 144

or, x = 72°

⇒ ∠MLP = ∠MPL = 72°

Now,as JK II ML

⇒ ∠LJK = ∠JLM = 22° ( Alternate pair of angles)

Now, by the measure of straight angle:

∠MLP + ∠JLM + ∠JLK = 180° ( Straight angle)

⇒ 72° + 22° + ∠JLK = 180°

or, ∠JLK = 86°

In , in ΔJLK

By ANGLE SUM PROPERTY: ∠JKL + ∠JLK + ∠LJK = 180°

⇒ ∠JKL + 86° + 22° = 180°

⇒ ∠JKL = 180 - 108 = 72 , or ∠JKL = 72°

Hence, from above proof , ∠MLP = 72° , ∠LJK = 22° , ∠JKL = 72° ,

∠KLJ = 86°

A shark was swimming at 300 feet below sea level. He swam 300 feet up toward the surface. How many feet above sea level is the s

Rom4ik [11]

Answer: the shark is at sea level

Step-by-step explanation: is you are 300 beneath the sea level that's -300 and if you go up 300 ft that +300. So 300+(-300) gives you 0 making the shark at sea level.

need help with error analysis assingment, im in high school and ive always struggled with math alot pls help

Given

A) The angles A and B are supplementary.

If,

$\begin{gathered} \angle A=x+6 \\ \angle B=7x+30 \end{gathered}$

B) The figure,

To find

A) The value of x.

B) The value of x.

Explanation:

A) It is given that,

Angle A and angle B are supplementary.

Then,

$\angle A+\angle B=180\degree$

Hence, the error is in the statement,

Since the angles are supplementary, when added together they equal 90.

As, the correct answer is when added together they equal 180.

That implies,

$\begin{gathered} x+6+7x+30=180 \\ 8x+36=180 \\ 8x=180-36 \\ 8x=144 \\ x=\frac{144}{8} \\ x=18\degree \end{gathered}$

Hence, the value of x is 18 degrees.

B) It is given that,

From, the figure the given angles are interior angles.

Also, the interior angles on the same side of the transversal is supplementary.

Which means when you add them they equal 180.

Hence, the error is in the statement,

Since the angles are adjacent, they are complementary angles.

Which means when you add them they equal 180.

As, the angles are interior angles on the same side of the transversal.

Also,

$\begin{gathered} 64+x=180 \\ x=180-64 \\ x=116\degree \end{gathered}$

Hence, the value of x is 116 degrees.
