Answer:

Step-by-step explanation:

So basically you have to do the Pythagorean Theorem here.

Which is =  a^2 + b^2 = c^2

So you'll put 35 in 'a' and 84 in 'b'

It'll be like this = 35^2 + 84^2 = c^2

So here, we are looking for 'c'

And 'c' is the hypotenuse

So,

Step 1: 35^2 + 84^2 = c^2

Step 2: You will use the exponents (but not for c)

=  1225 + 7056 = c^2

Step 3: You will now add 1225 + 7056 = 8281

Step 4: Now, square root 8281√8281 = 91

91 = c

Hope this helps! Please let me know if you get this correct!

What is the answer to x^2=4​
IrinaK [193]

Answer:

x = ± 2

Step-by-step explanation:

Given

x² = 4 ( take the square root of both sides )

x = ± \sqrt{4} = ± 2

Since 2 × 2 = 4 and - 2 × - 2 = 4

Solve the triangle.<br> A = 32°, a = 19, b = 14
Paha777 [63]

Answer:

A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36

Step-by-step explanation:

We have two sides of the triangle and we have an angle.

A = 32 °, a = 19, b = 14

We use the sine theorem to find the angle B.

We know that according to the sine theorem it is true that:

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

\frac{sin(32\°)}{19}=\frac{sin(B)}{14}

sin(B)=14*\frac{sin(32\°)}{19}\\\\B=Arcsin(14*\frac{sin(32\°)}{19})\\\\B=22.98\°

We know that the sum of the internal angles of a triangle is always equal to 180.

So:

C=180-32-22.98\\\\C=125.02\°

Finally we find the c side

\frac{sin(A)}{a}=\frac{sin(C)}{c}

\frac{sin(32\°)}{19}=\frac{sin(125.02)}{c}

0.02789=\frac{sin(125.02)}{c}

c=\frac{sin(125.02)}{0.02789}\\\\c=29.36
