How to find the power of area of a square 3.5² i know the answer is 12.25 but i want the formula of 3.5²

LiRa [457]

Answer:

$3.5^{2}$ = 3.5 * 3.5 = 12

square means: multiply the number by itself two times. so 3.5 * 3.5

cube ( $3.5^{3}$ ) means: multiply the number by itself three times. so 3.5 * 3.5 * 3.5

i hope u understand :)

To find the measure of ∠A in ∆ABC, use the___(Pythagorean Theorem, Law of Sines, Law of Cosines). To find the length of side HI

nadya68 [22]

Part 1) To find the measure of ∠A in ∆ABC, use

we know that

In the triangle ABC

Applying the law of sines

$\frac{a}{sin\ A}=\frac{b}{sin\ B}=\frac{c}{sin\ C}$

in this problem we have

$\frac{a}{sin\ A}=\frac{b}{sin\ theta}\\ \\a*sin\ theta=b*sin\ A\\ \\ sin\ A=\frac{a*sin\ theta}{b} \\ \\ A=arc\ sin (\frac{a*sin\ theta}{b})$

therefore

the answer Part 1) is

Law of Sines

Part 2) To find the length of side HI in ∆HIG, use

we know that

In the triangle HIG

Applying the law of cosines

$g^{2}=h^{2}+i^{2}-2*h*i*cos\ G$

In this problem we have

g=HI

G=angle Beta

substitute

$HI^{2}=h^{2}+i^{2}-2*h*i*cos\ Beta$

$HI=\sqrt{h^{2}+i^{2}-2*h*i*cos\ Beta}$

therefore

the answer Part 2) is

Law of Cosines

The endpoints of the diameter of a circle are (–3, –6) and (–7, 8). Find the x-coordinate of the center of the circle.

Crazy boy [7]

You need to find the midpoint of the line. To get x coordinate you take (x1 + x2)/2 which is (-3+-7)/2 = -10/2 = -5. Same thing applies for y.
