In the fist you have to know: a<span>ny angle opposite the head is equal in measurement.
so now we know o</span><span>ne angle in the triangle it is 82
</span><span>All corners of the triangle are equal 180
</span>so we have to do this 180-82=98
so we have to collection (4x+8)+(8x-6)=98
12x+2=98
12x=96
x=8
4(8)+8=40
the answer is 40

Stels [109]

Answer:

a) 0.1535

b) 0.4866

c) 0.8111

Step-by-step explanation:

The probability that the next call come within the next t minutes is:

$p(t) = 1 -e ^{- t/3}$

According to this model,

a) the probability that a call in comes within 1/2 minutes is $p(t) = 1 -e ^{- (1/2)/3}$ =0.1535

b) the probability that a call in comes within 2 minutes is $p(t) = 1 -e ^{-2/3}$ =0.4866

c) the probability that a call in comes within 5 minutes is $p(t) = 1 -e ^{-5/3}$ =0.8111

If sin 0=3/5, then cos 0=

vaieri [72.5K]

Answer:

$\frac{4}{5}$

Step-by-step explanation:

Given

sinΘ = $\frac{3}{5}$ = $\frac{opposite}{hypotenuse}$

Then the hypotenuse = 5 and one leg of the right triangle is 3

Using Pythagoras' identity to find the second leg (x)

x² + 3² = 5²

x² + 9 = 25 ( subtract 9 from both sides )

x² = 16 ⇒ x = 4

cosΘ = $\frac{adjacent}{hypotenuse}$ = $\frac{4}{5}$
