Answer:
The length of the hypotenuse is 2.4m
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse
α = 55°
o: opposite = 2.0m
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, hypotenuse, opposite)
we look at which meets those data between the sine, cosine and tangent
is the sine
sin α = o/ah
Now we replace the values and solve
sin 55 = 2.0/h
0.81915 = 2.0/h
h = 2.0 / 0.81915
h = 2.4415 m
round to the nearest tenth
h = 2.4415 = 2.4 m
The length of the hypotenuse is 2.4m
Answer:
8.48 = x
Step-by-step explanation:
sin45 = x / 12
12sin45 = x
8.48 = x
Answer:
Step-by-step explanation:
8x = 9x - 7
-x = -7
x = 7
9(7)-7= 63-7=56
8(7)= 56
13y+7+56=180
13y+63=180
13y=117
y=9
13(9)+7= 117+7= 124
5y-11+56=90
5y+45=90
5y=45
y=9
5(9)-11+9(7)-7= z
45-11+63-7=z
34+56=z
90=z
Answer:
its b
Step-by-step explanation:
This is a 4 step problem.
Find the probability of drawing a green marble the first time
<em>8 green marbles ÷ 17 total marbles </em>
Next, we find the probability of drawing a green marble the second time
<em>7 green marbles ÷ 16 total marbles </em>
Find the probability of drawing a green marble the third time
<em>6 green marbles ÷ 15 total marbles </em>
We<u> take away one</u> from the total marbles and green marbles each time because we are finding the probability that we draw a green marble <u>all three times </u>
Last step:
Multiply all the probabilities
× 
× 
The final answer is 7/85 or an 8% chance
If you were curious, the decimal version of this answer is <u>0.08235294</u>
