Question

Find m<1 and m<3 in the kite. The diagram is not to scale.

Answer 1

The first one ——angle 1 is 17 and angle 3 is 73

Answer 2

For this case they tell us that the sides DA and AB are equal, so we have that angle 1 also has a value of 17 degrees (just like the DAC angle).

Now we look for angle 3. By definition we have that the sum of the internal angles of a triangle is given by 180 degrees. Then we have that the first upper triangle of the kite is fulfilled:

$Angle 3 + 17 + 90 = 180\\Angle 3 = 180-90-17\\Angle 3 = 73$

Answer:

Angle 1: 17 degrees

Angle 3: 73 degrees
