I see this triangle is isosceles. Thus, it has 2 sides of length 8 and 2 angles of measure 30 degrees.

(30 deg) + (30 deg) + (angle A) MUST add up to 180 degrees.

Thus, 60 deg + Angle A = 180 deg, so that Angle A = (180 - 60) deg, or 120 deg (answer)

Help me understand please

erastova [34]

Answer:

V=pi x (r)^2 x h

V-volume r-radius h-height

V= pi x (3)^2 x 9

V= pi x 9 x 9

V= pi x 81

V= 254.47 (rounded)

The length of the red line segment is 8 and the length of the blue line segment is 4. How long is the major axis of the eclipse?

liraira [26]

The major axis of the eclipse is 12 units long

The given parameters can be represented as:

$Red = 8$

$Blue = 4$

See attachment for illustration

To solve this question, we make use of the following theorem

The distance between a point and the foci sums up to the major axis

This translates to:

$Major\ axis = Red + Blue$

$Major\ axis = 8 + 4$

$Major\ axis = 12$

The length of a square is 256m and the breadth is 238m what is the perimeter

nikitadnepr [17]

The perimeter is 988 meters

Further explanation:

The given square has different length and breadth which means that the given square is a rectangle.

The formula for perimeter of a rectangle is:

$P=2L+2W$

Given

Length=L=256m

Breadth=W=238m

Putting the values in the formula:

$P=2(256)+2(238)\\=512+476\\=988\ meters$

The perimeter is 988 meters.
