Answer:

1st question: BD=88

2nd question: AB=24

Step-by-step explanation:

1st question:

BD is the total length (7x-10) which is equal to BC+CD [(4x-29)+(5x-9)]

so we have:

7x-10=9x-38

28=2x

x=14

BC= 4*14-29=27

CD= 5*14-9=61

BD=88

2nd question:

Since BD=BC

5x-26=2x+1

3x=27

x=9

AC=BC+AB

BC=2*9+1=18+1=19

43=19+AB

AB=24

Answer:

d = 14

Step-by-step explanation:

$\sin \: 45 \degree = \frac{a}{7 \sqrt{2} } \\ \\a = 7 \sqrt{2} \sin \: 45 \degree \\ \\ a = 7\sqrt{2} \times \frac{1}{ \sqrt{2} } \\ \\ a = 7 \\ \\ \sin \: 30 \degree = \frac{a}{d} \\ \\ \frac{1}{2} = \frac{7}{d} \\ \\ d = 2 \times 7 \\ \\ d = 14$
