Arc AC would be 90 degrees because the line is bisects the straight line (180 Degrees)
Answer: 90 Degrees
Answer:
40°, 60° and 80°
Step-by-step explanation:
sum the parts of the ratio, 2 + 3 + 4 = 9 parts
Divide 180° ( sum of angles in a triangle) by 9 to find the value of one part of the ratio.
180° ÷ 9 = 20° ← value of 1 part of the ratio , then
2 parts = 2 × 20° = 40°
3 parts = 3 × 20° = 60°
4 parts = 4 × 20° = 80°
The angles in the triangle are 40°, 60°, 80°
Answer:
2
Step-by-step explanation:
1+1=2 so the answer is 2
Seems to be an arythmetic sequence
common difference is 3 (increases by 3 each time)
an=a1+d(n-1)
d=3
a1=8
an=8+3(n-1)
an=8+3n-3
an=3n+5
