Question

I need The answers now hellllp
step by step explaination​

Answer 1

1a. A

1b. C

2 and 3 you have to draw

4a. 90 degree angle

4b. 180 degree angle

5a. 112 degrees

5b. 145 degrees

Explanation:

for 5 you just subtract the given values from 360

Answer 2

1a) A

(both B and C intersect at A)

1b) not sure

2a) draw 270 degree angle

360/4 = 90

90+90+90 = 270 = 3/4

2b) draw an angle less than 90 degree to get an acute angle

3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees

90/2 = 45

but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it

3b) draw a 90 degree angle facing downward and thats 270 degree

hope you get what im trying to say if not you can ask me again

4a) acute angle (90 degree)

4b) reflex angle (180 degree)

5a) 112 degree

118 + 130 + x = 360

248 + x = 360

x = 360 - 248

x = 112

5b) 145 degree

360 - 215 = 145

im posting the solutions and the answers of your previous questions here

6a) a = 60 degree

6b) b = 27 degree

because sum of interior angles of a triangle is 180

7a) b = 60 degree and a = 30 degree

7b) x = 36 degree and x = 36 degree

isosceles triangle has 2 same angles and 1 different

x + x + 108 = 180

2x + 108 = 180

2x = 180 - 108

2x = 72

x = 72/2

x = 36

8a) x = 95 degree

8b) a = 100 degree

9) steps;

draw a line segment QR

draw 120 degree angle at point Q

now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O

now from point O, open your compass of same measurement and draw an arc that cuts the previous arc

now draw a line from point Q to join the new formed arc

now using a protactor measure both the newly formed angles
