Answer:
A. The ratios of the sine of the angle to the opposite side are the same.
Step-by-step explanation:
The law of sines is ...
sin(A)/a = sin(B)/b = sin(C)/c
You would have a 40% chance or a 2/5 chance because 5 numbers 1 through 5 would be 1 2 3 4 5 so 2/5 of the numbers are even, but 40% would also be the answer because 20% of 5 is 1, and 40% of 5 is 2. So 2 out of 5 are even so your answer is you have a probability of 40% or 2/5 toland on an even number. Please mark brainliest if this helped
Answer:
the middle one
Step-by-step explanation:
y/x
and so 6/8 = y/16
Answer:
x=1 y=7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation into the first
-5x +2(7x) = 9
Distribute
-5x +14x = 9
Combine like terms
9x=9
Divide by 9
9x/9 =9/9
x= 1
Now find y
y = 7(1)
y = 7
The length of the altitude AD is 12 units.
<h3>How to find the height of a triangle?</h3>
The height of the triangle can be found as follows:
We have to find an angle using cosine law before we can find the height.
Therefore,
20² = 13² + 21² - 2 × 21 × 13 cos B
400 = 169 + 441 - 546 cos B
400 - 610 = - 546 cos B
-210 = - 546 cos B
cos B = -210 / -546
cos B = 0.38461538461
B = cos⁻¹ 0.38461538461
B = 67.3810899783
B = 67.38°
Hence,
sin 67.38° = opposite / hypotenuse
sin 67.38° = AD / 13
cross multiply
AD = 13 sin 67.38°
AD = 11.9999882145
AD = 12 units
