Find the shaded area. First to answer (correctly) will get brainliest.

Mathematics

Virty [35]3 years ago

Answer:

2.27 m²

Step-by-step explanation:

The shaded area is the subtraction of the area of an equilateral triangle (with sides = 2 m) to the area of a square (with sides = 2 m)

Area of equilateral triangle = √3/4*a²

where a is the length of the sides of the triangle. Replacing with a = 2

Area of the equilateral triangle = √3/4*2² = √3 m²

Area of the square = a² = 2² = 4 m²

Shaded area = 4 - √3 ≈ 2.27 m²

Lerok [7]

Answer:

m (slope) = \frac{11}{2}

Step-by-step explanation:

point-slope form: m= \frac{y2-y1}{x2-x1}

(4, 5)   (2, -6)

x1  y1   x2  y2

-------------------

\frac{-6 - 5\\}{2 - 4} = m

-6 - 5 = -11

2 - 4 = -2

m = \frac{11}{2}

A cone has a volume of 226.08 cubic millimeters and a height of 6 millimeters. What is its
dezoksy [38]

Answer:

r≈5.36656314

Step-by-step explanation:

Since A=πr(r+\sqrt{h^2+r^2}) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+\sqrt{36+r^2}) so we get r≈5.36656314

Which postulate or theorem, if any, could be used to prove the triangles congruent? If not
inysia [295]
Question 11a)

We are given side BC equals to side CE and angle CBA equals to angle CED
We also know that angle ACB equals to angle ECD are equal (opposite angles properties)

We have enough information to deduce that triangle ABC and triangle CDE are equal by postulate Angle-Side-Angle (ASA)

---------------------------------------------------------------------------------------------------------------

Question 11b)

We are given side AB equal to side ED, side BC equals to side EF, and side AC equals to side DF
We have enough information to deduce that triangle ABC and triangle DEF congruent by postulate Side-Side-Side (SSS)

----------------------------------------------------------------------------------------------------------------

Question 11c)

We are given side AC equals to side DF, angle ABC equals to angle DEF, and angle BAC equals to angle EDF

We have enough information to deduce that triangle ABC congruent to triangle DEF by postulate Angle-Side-Angle (ASA)

-----------------------------------------------------------------------------------------------------------------

Question 11d)

We do not have enough information to tell whether this shape congruent or not
