Answer:
2 and 4.
Step-by-step explanation:
- 2 is not a square because a trapezoid does have 4 sides, but the sides are not parallel, or congruent. ↓
- 4 is not a square because similar to the trapezoid, it does have 4 sides, but is not parallel nor congruent. ↓
- Although some people consider a rectangle a square, it is a square and also is not because it has 2 pairs of parallel sides, instead of all 4 sides being parallel.
Hope it helps!
Answer:
A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.
Step-by-step explanation:
x = 19,
Putting value of x to find m∠ABC and m∠ACB
m∠ABC = (4x – 12)°
m∠ABC = (4(19) – 12)°
m∠ABC = (76 – 12)°
m∠ABC = 64°
m∠ACB = (2(19) + 26)°
m∠ACB = (38 + 26)°
m∠ACB = 64°
now we know sum of angles of triangle is 180°. We can find the measure of third angle.
180 = 64+64 +x
x= 180 - 64 - 64
x = 52°
A triangle is equilateral if all three angles are same. but here two angles are 64° but third angle is 52°. so, Yin is incorrect.
Step-by-step explanation:
1/2(4-14y)=y+50
1/(8 - 28y) = y + 50
8y - 400 - 28y² +
Now you can solve
Answer:
b
Step-by-step explanation:
The complimentary event is the probability of it not raining. The probability of that is 1-2/5 = 3/5.
