We know that a = b and c = 30

Since b + 30 = 90, we know b = 60.
That means a = 60

a = 60
b = 60
c = 30

Answer:

a) 60°

b) 60°

c) 30°

Step-by-step explanation:

Get 60 by subtracting 30 from 90 because the angle is a right angle. Since b is identical to a and also is a right triangle, it will also be 60. Get c as 30 by looking at its vertical angle across from it.

In triangle XYZ, an exterior angle to angle X had measure 100° and an exterior angle to angle Z has measure 120°. Which side of
DaniilM [7]

Answer:

Side YZ is the longest

Step-by-step explanation:

The longest side is across from the largest angle.

Angle X must be 80° because its exterior angle is 100° and they're supplementary. Angle Z is 60° for the same reason. Inside a triangle is always 180°, and since the measures of angle Z and X add up to 140°, so there's 40° left, meaning angle X is the largest.

Angle X is across from size YZ, so that's the longest
