YES

We know: $(a^n)^m=a^{n\cdot m}$

We have: $x^6=x^{2\cdot3}=(x^2)^3$

Find the Measurements of the arc or angle indicated.

mamaluj [8]

Answer:

5) 126

6) 116

Step-by-step explanation:

5) m∠NLM is equal to the arc MN, or 63x.

To find x, use the inscribed angle theorem.

32x − 1 = ½ (63x)

64x − 2 = 63x

x = 2

Therefore:

m∠NLM = 63(2)

m∠NLM = 126

6) Using the same logic:

9x + 4 = ½ (19x + 2)

18x + 8 = 19x + 2

x = 6

Therefore:

mYX = 19(6) + 2

mYX = 116

One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necess

Amanda [17]

Answer:

17.7 cm

Step-by-step explanation:

One of the legs of a right triangle measures 12 cm and the other leg measures 13 cm find the measure of the hypotenuse if necessary round the nearest 10th

To find the Hypotenuse of a right angle triangle, we solve using Pythagoras Theorem

Hypotenuse ² = Opposite ² + Adjacent ²

Hypotenuse = √Opposite ² + Adjacent ²

Opposite = 12 cm

Adjacent = 13 cm

Hence,

Hypotenuse = √12² + 13²

= √144 + 169

= 17.691806013 cm

Approximately = 17.7 cm

Therefore, the measure of the Hypotenuse is 17.7 cm
