PLEASE HELP

For Question 13 :∡ 1 = 130°; ∡ 2 = 50° ∡ 3 = 130°

For Question 14 :∡ 1 = 65°; ∡ 2 = 115° ∡ 3 = 65°

Step-by-step explanation:

Question 13:

There is multiple ways to solve those questions. However I will stick with the simple way.

1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that ∡ 1 + the ∡ 50° = 180°

Resoectivelly

180° - 50° = ∡1

180° - 50° = 130°

∡ 1 = 130°

3) ∡ 2 + ∡ 1 = 180°

We already ∡ 1 from step 2, then

∡ 2 = 180° - 130°(∡1)

∡ 2 = 50°

4) ∡ 2 + ∡ 3 = 180°

∡ 3 = 180° -  50° (∡ 2)

∡ 3 = 130°

Question 14 1) We know that a straighteangle is = to 180°

2) Acording to the statment on step one we will say that

angle 1 + the angle  115° = 180°

Resopectivelly

180° - 115° = ∡ 1

180° - 50° = 65°

∡1 = 65°

3) ∡ 2 + ∡ 1 = 180°

We already∡ 1 from step 2, then

∡ 2 = 180° - 65°(∡1)

∡ 2 = 115°

4) ∡ 2 + ∡ 3 = 180°

∡ 3 = 180° -  115° (∡ 2)

Have fun

a

step-by-step explanation:

f . i can go whenever i feel like it bc it is confidential meaning only i would know how much i deposited besides the bank and they wouldnt care bc when you make a deposit you are using their services which means they are using there competition and gaining more customers

and if they dont well then thats less customers for them in a less profitable way
