Answer:
3=140°
Step-by-step explanation:
Answer:
- a. ∠Y, ∠W, ∠X
- d. 75°
- d. 5
Step-by-step explanation:
1. The sides, shortest to longest, are 5, 10, 12. The angles opposite are in the same order (smallest to largest). Those angles are ∠Y, ∠W, ∠X.
__
2. The triangle isosceles, so the base angles are equal. The sum of angles in a triangle is 180°, so you have ...
30° + 2x = 180°
15° + x = 90° . . . . . divide by 2
x = 75° . . . . . . . . . . subtract 15°
__
3. The midline of a triangle is half the length of the base it is parallel to, so ...
ML = 10/2 = 5
It is a <em>midline</em> because it joins the midpoints of two sides of the triangle.
Answer:
≈83.33
Step-by-step explanation:
Mean is the average
so
Mean = [79+42+86+103+79+111] / 6
= 500/6
≈ 83.33
In one minute printer can make 12/3=4 photos
1st box so in 4 minutes it will make 4*4 = 16 photos
2nd box 24 images will be in 24/4= 6 minutes
3rd box in 9 minutes it will make 9*4=36 images
4th box 40 images will be 40/4=10 minutes
