1. ∠A = 70, ∠B = 50, ∠C = 60

2. y = 52

Step-by-step explanation:

1.

The exterior angle and the interior to that would have a SUM of 180.

So, if exterior to ∠C is 120, we can say:

exterior to C + ∠C = 180

120 + ∠C = 180

∠C = 180 - 120 = 60

∠C = 60

We also know sum of all 3 angles in a triangle is 180. Thus we can write:

∠A + ∠B + ∠C = 180

2x + x + 15 + 60 = 180

3x + 75 = 180

3x = 105

x = 105/3

x = 35

Thus,

∠A = 2x = 2(35) = 70

∠A = 70

and

∠B = x + 15 = 35 + 15 = 50

∠B = 50

2. The angle "4x" and its exterior angle "5x" is a straight line, so the sum is 180. Now, we find x:

4x + 5x = 180

9x = 180

x = 180/9

x = 20

So, we can say the angle "4x" is 4(20) = 80

We know sum of 3 angles of a triangle is 180, thus:

y + 48 + 80 = 180

y + 128 = 180

y = 180 - 128

y = 52

i hope this is what you were looking for.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
