Answer:

Q1.

AC is the greatest side, therefore is hypotenuse. AB and BC are legs.

B is 90 deg as the two legs cross at this point.

<u>Ratios:</u>

  • sin = opposite / hypotenuse
  • cos = adjacent / hypotenuse
  • tan = opposite / adjacent

BC is opposite to A and adjacent to C

AB is adjacent to A and opposite to C

  • sin A = cos C = 8/10 = 4/5
  • cos A = sin C = 6/10 = 3/5
  • tan A = cot C = 8/6 = 4/3
  • tan C = cot A = 6/8 = 3/4

What is the measure of the smallest interior angle of the hexagon shown?
yan [13]
<h3>Answer:  C) 70 degrees</h3>

=========================================================

Explanation:

We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees

Lets add up the angles, set the sum equal to 720 and solve for x

x+2x+115+2x+115+2x = 720

7x+230 = 720

7x = 720-230

7x = 490

x = 490/7

x = 70

This makes angle 2x = 2*70 = 140 degrees

We see that x = 70 is the smallest angle, so that's why C is the answer.

FIRST ANSWER GETS BRAINLIEST!!!
maksim [4K]

I believe it is A and C.

There are 6 slots on the wheel, so both the numbers in A and E can be divided/multiplied to fit this criterion.  For example, 3 times 2 is 6 (the number of gender slots) and 1 times 2 is two, so two out of 6 art teachers will be female.

I hope this helps!!!
