Question

Find the missing measure of each triangle.

A= 50, B= 70 c= ?

Answer 1

Favorite Answer

*Pythagorean Theroem: a^2 + b^2 = c^2

*The "c" variable represents the hypotenuse (largest number).

First: substitute the numbers with the corresponding variables.

50^2 + 70^2 = c^2

50*50 + 70*70 = c^2

2500 + 4900 = c^2

7400 = c^2, or c^2 = 7400

Sec: eliminate the exponent - find the square root of both sides.

√c^2 = +/- √7400

c = +/- √(2*2*2*5*5*37)

c = +/- 2(2)(5)√2*37

c = +/- 20√74 or, c = +/- 86.02

*The hypotenuse has to be larger than 60.

Answer 2

all angles of a triangle have to add up to 180

therefore 180-70-50 =60

c=60

Answer 3

c=60

Answer 4

with the following details you gave, it still needs a third parameter like is it a right triangle or what for you to find the third measure of the tiangle.
