Draw a perpendicular segment from point C to the midpoint of AB. Using the trig sine function sin 80 = x/6 which gives 5.91 for the perpendicular segment. Using the formula A=1/2bh, A= 1/2 x5.91x2sqrt 2  A= 8.4

A, B, and C are midpoints of ∆XYZ. What is the length of yz
beks73 [17]

Answer:

Step-by-step explanation:

Comment

When you join 2 consecutive midpoints with a line between them, the length of that line is 1/2 the length of the side opposite the line you just drew.

In other words 24 is 1/2 the length of yz.

Solution

1/2 yz = AB

AB = 24

1/2 yz = 24                 Multiply both sides by 2

2(1/2 yz) = 2*24

yz = 48

Answer

yz = 48

PQ¯¯¯¯¯ and PR¯¯¯¯¯ are tangent to ⊙ S. Identify PQ.<br> pls help 30 points
olga_2 [115]

Answer:

9

Step-by-step explanation:

Because line PQ and line PR are both tangent to circle S, it would result in them being equal. So first to find PQ, you would have to find the value of variable x. To do this you would set both equations equal to each other and solve

6x - 9 = 2x + 3

-2x       -2x

4x - 9 = 3

    +9   +9

4x = 12

x = 3

Now you have to substitute 3 back into the equation for PQ:

6(3) - 9

18 - 9

= 9

Resulting in PQ = 9, to check your answer, take the value of x (3) and substitute it into PR and you should also get 9

2(3) + 3

6 + 3

= 9

The height of a triangle is 4 times its base. The area of the triangle is 288 square. Find the base and the height of the triang
Vanyuwa [196]
\bf \textit{area of a triangle}\\\\&#10;A=\cfrac{1}{2}bh\qquad &#10;\begin{cases}&#10;b=base\\&#10;h=height\\&#10;----------\\&#10;h=4b\leftarrow &#10;\begin{array}{llll}&#10;\textit{height is 4}\\&#10;\textit{times the base}&#10;\end{array}\\&#10;A=288&#10;\end{cases}\implies 288=\cfrac{1}{2}\cdot b\cdot 2b

solve for "b", to see what the base is

what about the height?  well, h = 4b
