Answer:
I wasn't sure if you meant centimeters, inches or degrees. But since I don't know, I'll answer all three.
Step-by-step explanation:
Centimeters- Possible
Inches- Possible (Extremely big. I suggest using a big whiteboard to draw out)
Degrees- Impossible (All degrees in a triangle have to add up to 180)
Answer:
z=10 because 3x5=15 and you do the same to the other number.
Step-by-step explanation:
Answer:
- 78.33°
- 71°
Step-by-step explanation:
1) The sum of angles in a triangle is 180°, so ...
(x +3)° +(x +24)° +(x -10)° = 180°
3x +17 = 180 . . . . . . . . divide by °, collect terms
3x = 163 . . . . . . . . . . . .subtract 17
x = 54 1/3 . . . . . . . . . . .divide by 3
m∠B = (x +24)° = (54 1/3 + 24)°
m∠B ≈ 78.33°

2) An exterior angle is equal to the sum of the opposite interior angles.
m∠ACD = m∠A + m∠B
(3x -10)° = (x +9)° + 105°
2x = 124 . . . . . . . . . . . . . . divide by °, add 10-x to both sides
x = 62 . . . . . . . . . . . . . . . . divide by 2
m∠A = (x +9)° = (62 +9)°
m∠A = 71°
