Mathematics
1 answer:
Luba_88 [7]3 years ago
3 0

Answer:

a = 60

b = 60

Step-by-step explanation:

We know that BC is 90°, because of the square thingy.

YB is 30°.

Now we do 180 - 30 - 90 = 60 (180 is the straight angle)

60  = b

Then a is the same.

Luba_88 [7]

Answer:

P = 8\sqrt{2} + 10 + 2\sqrt{6}

Can only be simplified through calculator using decimal equivalents.

Step-by-step explanation:

The perimeter of a rectangle is the formula P=2l+2w. Here l=4\sqrt{2} and w=5+\sqrt{6}. So the perimeter is:

P= 2l+2w\\P = 2(4\sqrt{2} ) + 2(5+\sqrt{6} )\\P = 8\sqrt{2} + 10 + 2\sqrt{6}

The probability that it will snow in a certain town on January 1st is 0.29 find the probability that in a given year it will not
Mashutka [201]

Answer:

0.71


Step-by-step explanation:

The probability is a chance of an event happening. The probability of assured event is 100% or 1.

If there is no chance of an event happening the probability is zero (0).

The probability of snowing = 0.29

The probability of not snowing = 1 - 0.29

                                                   = 0.71

312=52W

W= 312/52

W=6 in

Hence the width is 6in
