Answer:

"C" =14

Step-by-step explanation:

14+(-12)=-12+c

-12+c=14+(-12)

-12+c=14-12

-12+c+12=2+12

c=14

Simplify brackets

14 + -12 = -12 + c

Cancel -12 on both sides

14 = c

Switch sides

<u>c = 14</u>

FinnZ [79.3K]

Answer:

The length of the hypotenuse ≈ 39.7 cm

Explanation:

Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.

The equation for Pythagorean calculation is:

(hypotenuse)² = (first leg)² + (second leg)²

In the given, we have:

first leg = 30 cm

second leg = 26 cm

Substitute with the givens in the above equation to get the hypotenuse as follows:

(hypotenuse)² = (30)² + (26)²

(hypotenuse)² = 1576

This means that:

either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted

or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative

Hope this helps :)
