MATH HELP PLEASE! ( please show all work)

Mathematics
1 answer:
natita [175]2 years ago
6 0

Answer:

Step-by-step explanation:

Sin(42) = n/21

n = 21 * sin(42)

n = 21 *  0.6691

n = 14.052

Cos(42) = m / 21

21 * cos(42) = m

m = 21 * 0.7431

m = 15,61

Theta + 42 = 90

Theta = 90 - 42

Theta = 48

I need help with geometry.<br> Find x.
I am Lyosha [343]

Answer:

Part 9) x=5  

Part 10) x=-9  

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

Part 9) we know that

Point Q is the midpoint segment XY (QY=QX)

Point R is the midpoint segment XW (RW=RX)

Applying the Midpoint Theorem

RQ is parallel to WY

and

RQ=\frac{1}{2}WY  

we have

RQ=2x-3\\WY=x+9

substitute

2x-3=\frac{1}{2}(x+9)  

solve for x                  

4x-6=(x+9)          

4x-x=9+6

3x=15  

x=5  

Part 10) we know that

Point B is the midpoint segment TS (BS=BT)

Point C is the midpoint segment RS (CS=CR)

Applying the Midpoint Theorem

BC is parallel to TR

and

BC=\frac{1}{2}TR  

we have

BC=x+19\\TR=x+29

substitute

x+19=\frac{1}{2}(x+29)  

solve for x

2x+38=(x+29)  

2x-x=29-38          

x=-9
