In triangle RG shown below. m 63 and m 30 Which of the following is the<br> 63
Tatiana [17]

Answer:

The value of the hypotenuse is 69.77 meters.

Step-by-step explanation:

To determine, in triangle RG, the value of its hypotenuse if its sides measure 63 meters and 30 meters, the following calculation must be performed, applying the Pythagorean theorem:

63 ^ 2 + 30 ^ 2 = X ^ 2

3969 + 900 = X ^ 2

√ 4869 = X

69.77 = X

Therefore, the value of the hypotenuse is 69.77 meters.

miskamm [114]

Answer:

t + 8° > 82°

Step-by-step explanation:

Given that :

Let t = temperature when Susanne checks at 11:00

If t rises by 8 more degrees, it will break the record high temperature for that day

Record high temperature for the day = 82 degree

Hence,

Temperature at 11:00 + 8° > record high temperature for the day

t + 8° > 82°

Suppose you roll a special 34-sided die. What is the probability that the number rolled is a "1" OR a "2"?
nika2105 [10]
Rolling a 1 or a 2 are mutually exclusive events (if you roll a 1, you could not have rolled a 2, and vice-versa), so the probability here is additive:

P(1 or 2) = P(1) + P(2) = 1/34 + 1/34 = 2/34 = 1/17.

So the probability of rolling a 1 or a 2 is 1/17.
