Answer:

E. 443.4 ft²

Step-by-step explanation:

Since it is a regular triangle, it means all three sides are of equal lengths and all angles are of the same degree measure.

Therefore, all sides = 32 ft each

Each equal angle = 60° (sum of all angles = 180)

The area of the triangle can be calculated using the formula, ½*a*b*sin(C),

Where,

a = 32 ft

b = 32 ft

C = 60°

Plug in the values

Area = ½*32*32*Sin(60)

Area = 443.4 ft² (nearest tenth)

State the type of angles and solve for the given variable.

Evgen [1.6K]

Step-by-step explanation:

the given pair is Alternate Exterior Angle

so their values are equal so,

→ 2x + 26 = 3x - 33

→ 2x - 3x = -33 - 26

→ x = 59

therefore option C is correct

hope this answer helps you dear...take care and may u have a great day ahead!

If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f + g)(x).

pishuonlain [190]

Answer:

(f+g)(x) = $3x^{2} - 6$

Step-by-step explanation:

First, lets understand what (f+g)(x) means.

(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).

So, this is what the equation looks like when you substitute the functions in to (f+g)(x):

(f+g)(x) = $(2x^{2} +1) + (x^{2} -7)$

Now, combine like terms and Simplify:

(f+g)(x) = $3x^{2} - 6$

This is your final answer.

Timed help asap free 30 points after if correct find the value of the polynomial x^2-3xy+1/2 y^2 if x=3,y-2

BARSIC [14]

Answer:

Ans: 29

Step-by-step explanation:

soln:

Given,

x=3 and y=-2

Now,

x^2-3xy+1/2y^2

= 3^2-3×3×(-2) +1/2(-2)^2

= 9+18+4/2

= (18+36+4) /2

= 58/2

= 29 Ans
