Answer:

See below

Explanation:

15)

In the right-angle triangle, once one of the angles is 44º, then, the unknown angle is
.

180 = 44 + 90 + x

180 = 134 + x

x= 46

The angle
of the other triangle plus the angle
of the right-angle triangle is equal to 90º, therefore they are complementary angles.

So,

90 = x + y

90 = 46 + y

y=44

To find ?, we have

180 = 58 + 44 +?

? =78

16)

The sum of the internal angles of the triangle with angles 50º and 25º is equal to 180º, therefore, the other angle is

$180 = x + 50 + 25\\180 = x+ 75\\x=105$

Once the angles are opposite, they are the same. For the triangle with the 36º angle, we have

180 = 36 + 105 + y

180 = 141+ y

y=39

?=39
