Answer:

2.a)31°

b)135°

3.a)72°

Step-by-step explanation:

2a) Angles in a straight line add up to 180°

180-62=118°

since in an isosceles triangle base angles are equal 62÷2=31°

b)sum of interior angles=180(n-2)

180(8-2)=1080°

each angle is 1080÷8=135°

3.a) Exterior angle=360/n

=360÷5=72° each

How do I figure out the length of two unknown sides of an isosceles right triangle, when the hypotenuse is 8.6m (c=8.6m)?

irinina [24]

Hey, for this problem, you are going to want to use SOH CAH TOA, {Sine, Cosine or Tangent} since the hypotenuse is involved, you can use sine or cosine. {I used Cosine}.
cos(45°)=x/8.6 {x is missing side}
0.7071=x/8.6
0.7071×8.6=x/8.6 ×8.6
6.08=x

P.S.: Hope I Helped :)
