Question

Please answer this im so confused

Answer 1

Step-by-step explanation:

1. Since,in question 21 the trspezium is an isoseles tapizium
2. therefore,9x-17=4x+28
3. 5x=45
4. x=9
5. therefore q=9x-17
6. =9*9-17
7. =81-17
8. q=64
9. therefore 2t=360-128(since its isoseles triangle therefore adjacent base angles are equal)
10. 2t=23
11. t=116

• In question 28

1. 2(K+M)=360
2. 2(3x+16 + 11x-18)=360
3. 2(14x-2)=360
4. 28x-4=360
5. 28x=364
6. x=13
7. J=K
8. Isoleses angles are equal
9. 3x+16=J
10. 39+16=J
11. J=55

• In question 29

1. Bd=Ec (Congeruent sides of congurent trisnle are equal,BED~=CDE)
2. 8x-27=2x+33
3. 6x=60
4. x=10
5. Therefore,Bd=8x-27
6. Bd=80-27
7. Bd=53
