We will use the PEMDA method. 
<span>5 • [(14 + 3 • 30) + 120] + 103 – 10
</span>          first, add what's in the parenthesis
5 • [(17 <span>• 30) + 120] + 103 - 10
</span>          now let's multiply what's in the parenthesis
5 <span>• [(510) + 120] + 103 - 10
</span>           continue to simplify what is in the parenthesis
5 <span>• [630] + 103 - 10
</span>  
            now let's multiply 
3150 + 103 - 10

no division? let's subtract!


3150 + 93 

last step (:

Determine whether each of the following pairs of angles have equal measures.
Hatshy [7]

The pairs of angles that  have equal measures are:

  • LJP
  • NJR
  • MJP
  • PJR

The pairs of angles that do not  have equal measures are:

  • MJK
  • PJR
  • KJR
  • MJP
  • KJL
  • LJM

<h3>What is an angle?</h3>

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

Both MJK and  PJR can be seen as (Unequal angles)

The angle MJK  is ( 90 degrees), then  angle PJR will be ( 48 + 46 )= 94 degrees

Both LJP and NJR  can be seen as ( Equal angles)

The measure of angle LJP = 48 + 46 + 48 = 142 degrees

The measure of angle NJR = 48 + 48 + 46 = 142 degrees

KJR & MJP = Unequal

The angle KJR will now be [ 360 - (46+48+48+46+90) ]

= 82 degrees

The  angle MJP  will be ( 94 degrees)

Both KJL & LJM  are Unequal, then

The angle KJL  will be  42 degrees, then angle LJM  will be ( 90 - 42 )

= 48 degrees

The sum of two numbers is 45 and the different is 21.what are the numbers
ryzh [129]
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12

A slide 4.4 m long makes an angle of 33 with the ground. How high is the top of the slide above the ground
svp [43]
Using the information given we will only need the Cosine and Sine equations.  i made a diagram (cant take a picture, in my study hall) labeled the sides of the triangle A, B, and C.  with C as the hypotenuse, A as the Opposite, and B as the adjacent (will not be needed as A is the height). i will be rounding the th nearest thousandth. 
Using Sine (SIN=Opposite/Hypotenuse), we can find A.

SIN(33)=A/4.4

SIN(33)≈.545

.545≈A/4.4

now multiply each side by 4.4 to get rid of the division

(.545*4.4)≈((A/4.4)4.4)

2.396≈A
 

so the answer would be that the slide is about 2.396 M high
