Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do.

Answer:
10
Step-by-step explanation:
From past data:
Fraction of lily sold :
Total flowers / number of lily
Total flowers = 14
Number of lily = 7
Fraction of lily = 14 /7 = 1/2
Going by these ;
Expected number of lilies in the next 20 bouquets sold :
Fraction of lily * number of flower in bouquet
1/2 * 20
= 10 lilies
Answer:
Step-by-step explanation:
left side is 120 word per minute and the right side is 185 word per minute
110 students are going on a trip, and each student needs one water bottle.
So we multiple 110 students* 1 water bottle each to get 110 water bottles are needed for all the students.
There are 6 water bottles in a pack- and we need 110 water bottles.
So divide the number of water bottles needed by the amount in a pack.
110/6= 18 1/3
We need 18 packs a little bit more- so we round 18 up because we can't buy 1/3 of a pack or have students go thirsty.
So we need 19 packs of water for the students on the trip.
A² + b² = c²
20² + n² = (n+2)²
400+ n² = (n+2)(n+2)
400 + n²=n² + 2n + 2n +4
400 + n² = n² +4n +4
400 + n²-n² = n²-n² + 4n+4
400 = 4n + 4
400-4 = 4n +4-4
396 = 4n
396/4 = 4n/4
n= 99
20²+ 99² = (99+2)²
400 + 9801 =10201
10201=10201
