Find the area of the trapezoid. Answer options: 60sqrt3, 52sqrt3, 44sqrt3 -24, 44sqrt3

antoniya [11.8K]

Answer:

= 52sqrt3

Step-by-step explanation:

Area of a trapezium is given by the formula;

1/2(a+b)h

Where a and b are the parallel sides and h is the perpendicular height.

a = 15 ft, b= 11 ft and h = 4√3

Therefore;

Area = 1/2 (15+11) 4√3

= 1/2 × 26 × 4√3

= 52√3 ft²

Find the exact value of csc ø, if cos ø= 1/9; 180° less ø less than 270°

Iteru [2.4K]

Answer:

The answer to your question is: the first option - 9/ $\sqrt{80}$

Step-by-step explanation:

Process

cosФ = adjacent side / hypotenuse

-1/9 = adjacent side / hypotenuse

adjacent side = -1 hypotenuse = 9

c² = a² + b²

b² = c² - a²

b² = 81 - 1

b = $\sqrt{80} \\$ b = opposite side

But b is negative because we are in the third quadrant.

b = - $\sqrt{80}$

Finally csc Ф = hypotenuse / opposite side

csc Ф = - 9 / $\sqrt{80}$

-(r+4) = -3 solve each expression plz explain step by step so i can understand

Ugo [173]

There’s an invisible 1 in front of the minus sign and an invisible 1 in front of the variable.

-1(r+4)=-3 —> -1 times 1r = -1r. -1 times 4 = -4
Multiply inside the parentheses.

-1r-4=-3

Now add 4 to both sides.

-1r-4=-3
+4=+4
-1r = 1
Now divide

R= -1
