Answer 1

Answer: (1: 70 degrees) (2: 110 degrees) (3: 35 degrees)

Step-by-step explanation:

For the first triangle, we know that the angles in total add up to 180 degrees. You already know two angles (40 and 70).

Let's, for now, label angle 1 as x.

40 + 70 + x = 180, since the sum of the angles add up to 180

110 + x = 180, no problems right?

110 - 110 + x = 180 - 110

x = 70

Now there's angle 2.

Let's label angle 2 as y.

We know angle 1 by now, and we should know that y + 70 = 180, since the two angles form a line together. A line is always 180 degrees.

y + 70 = 180

y + 70 - 70 = 180 - 70

y = 110

Now there's the last angle, angle 3

Let's label angle 3 as z

Repeating what we did for angle 1, we already know two angles (110 and 35)

110 + 35 + z = 180

145 + z = 180

145 - 145 + z = 180 - 145

z = 35

There you have it! The answer, but this was the long way. The short way is much simpler, but harder to teach without a one-on-one lesson.

Don't forget units!
