Question

can anyone explain this please​

Answer 1

Answer:

Step-by-step explanation:

we know the triangle sum property of 180. to find interior x

first figure 30 + 40 + x = 180

70 + x = 180

180 - 70 = x

110 = x

but we need to find exterior here

so the straught line will be a 180. so 180 - 110 = 70

so for first figure ans is 70

same solution comes 60 in interior angle, to find exterior we will -60 from 180 which comes 120. it means for second figure ans is 120

2ND QUESTION

1ST FIGURE

180 - 100 + 70 + X = 180

80 + 70 + X = 180

150 + X = 180 = 180 - 150 = X

30 = X

SAME FOR FIGURE 2ND

WE GET 60 + 60 + X = 180

120 + X = 180

180 - 120 = X
