Step-by-step explanation:
<u>Arc length formula:</u>
<u>Substitute values:</u>
- s = 2*3.14*15(80/360) = 20.93 in
9 the smallest angle is always opposite the smallest side
Answer: choice d, angle B
They couldn't match the choice letters with the angles? Geez.
10. That's an isoscles triangle
d + d + 116 = 180
2d = 64
d=32
choice a
11. 62+45+k=180
k=180-107 = 73
choice b
Answer:
A.
<em>Brainliest, please!</em>
Step-by-step explanation:
In order to prove two triangles similar by AA, two angles in one triangle must be congruent to the opposite angles in the other. A is the only option that works as B and C are sides, which aren't relevant, and D, while an angle, doesn't make sense.
The mean is the average. If the mean of 4 letter (a,b,cd) is 12, the sum of them would be 12x4 =48
Now add e to the total: 48 + 50 = 98
The mean is the total divided by the quantity:
Mean = 98 /5 = 19.6
