(image) The figure below is an isosceles triangle surmounted by a semi-circle. Find the area of the entire region.

S_A_V [24]

Answer:

12.53

Step-by-step explanation:

∠BCA = (180°-40°)/2 = 70°

Laws of Sines: CA/sin 40° = AB/sin 70° = 5/sin 70°

CA = 5/sin 70° * sin 40° = 3.40

area of semicircle CA = (3.1416 * 1.70²) / 2 = 4.54

By Heron's Formula, area of triangle ABC:

1/4 √(a+b+c) (a+b-c) (b+c-a) (c+a-b) = 1/4 * √13.4*3.4*3.4*6.6

= 7.99

Entire region area = 4.54 + 7.99 = 12.53

x−2

−4+

−2

x−2+

x(Add 2/5x to both sides)

x−4=−2

x−4+4=−2+4(Add 4 to both sides)

x=2

(Divide both sides by 2/5)

x=5

HELP ASP PLS I WILL GOVE BRAINIST PLS PLS PLS HELPPPP picture below

belka [17]

We can solve this problem in three steps.

1) find the area of the square

$a=lw\\\\a=(7.5)(6)\\\\a=45ft^{2}$

2) find the area of the triangle

$a=\frac{1}{2}bh\\\\a=\frac{1}{2} (6)(4)\\\\a=12ft^{2}$

3) add the areas together

$a=45+12$

a = 57 ft²
