C 75 that’s what it is on apex
Answer:
C 9 *x^2 y^ 4 y^ 1/2
Step-by-step explanation:
(81x^4y^9)^1/2
We know that (ab)^1/2 = a^1/2 *b^1/2
(81) ^1/2 * (x^4) ^1/2 * (y^9)^1/2
We know that a^b^c = a^ (b*c)
(81) ^1/2 * (x^(4*1/2) * (y^(9*1/2)
9 *x^2 y^ 9/2
We know that y^9/2 = y^4 y^1/2
9 *x^2 y^ 4 y^ 1/2
Answer:
7.9 ft
Step-by-step explanation:
The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.
Side 
is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.
<em>Thus, we can write:</em>
<em>Cross multiplying, we can solve for :</em>
Rounding to nearest tenth, we have 
ft.
The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
