Answer:

20.5

Step-by-step explanation:

By the Triangle Midsegment Theorem, the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side. Therefore, (1/2)FH ≡ IH, (1/2)HG ≡ HJ. Knowing that IJ = 8 gives you the presidence to solve for the perimeter.

Find the equation of the line that passes throughP(6,0) andQ(1,−1).
yarga [219]

Answer:

Step-by-step explanation:

y=mx+b where m is the slope and b is the y intercept

m=(y2-y1)/(x2-x1), we have points (6,0) and (1,-1)

m=(-1-0)/(1-6)=1/5 so we have

y=x/5+b, using point (6,0) we can solve for b

0=6/5+b

b=-6/5

y=x/5-6/5 or more neatly

y=(x-6)/5

I need help, I don’t understand.
Sergeeva-Olga [200]

Answer:

angle 3 + angle 5 = 180°( co-interior angles)

120°+6x=180°

6x=60°

x=10°

therefore, angle 5= 6x=6×10°=60°

What is the approximate area of a sector with radius equal to 8 and measure of arc equal to 300°?
zimovet [89]
Sector Area = (central angle / 360) * PI * radius^2
Sector Area = 300 / 360 * PI * 8^2
Sector Area = (5/6) * 64 * PI
Sector Area = 53.3 * PI
