Answer:

Let "a", "b" and "с"  be sides of the triangle ("с" is the longest side).

The triangle will be:

right if       a² + b² = c²

аcute if     a² + b² > c²    

obtuse if   a² + b² < c²    

a.

a=3, b=4 and c=5

a² + b² = 3² + 4² = 9 + 16 = 25   and   c² = 5² = 25

25 = 25   ⇒  right triangle.

b.

a=5, b=6 and c=7

a² + b² = 5² + 6² = 25 + 36 = 61   and   c² = 7² = 49

61 > 49   ⇒  аcute triangle.

c.

a=8, b=9 and c=12

a² + b² = 8² + 9² = 64 + 81 = 145   and   c² = 12² = 144

145 > 144   ⇒  аcute triangle.

The earth is closer to the sun during summer in the northern hemisphere than it is during winter.
Nataly_w [17]
Salutations!

The Earth is closer to the sun during summer in the Northern Hemisphere than it is during winter. True or False?

True. The Earth is closer to the sun because during the summer, the sun rays are directly hitting towards the Northern Hemisphere which makes it hot. During the winter, the sun rays are not directly hitting, thus, its cooler in winter than in the summer.

Hope I helped :D
