4. Please answer! I’ll give brainliest! Please show evidence:))

G = 50

H = 80

I = 50

Step-by-step explanation:

Angle in a triangle is equal to 180. This means that we will equal all the angles to 180

2x + 2x + 4x-20 = 180

8x - 20 = 180

8x = 180 + 20

8x = 200

x = 200 / 8

x = 25

G = 2 * 25 = 50

I = 2 * 25 = 50

H = 4 * 25 - 20

H = 100 - 20 = 80

f

step-by-step explanation:

f

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
