When u add it stays the same but for subtraction u change the sign.
Example: 2- (-5)=7
Answer:
68°
Step-by-step explanation:
As BA⊥BD, so ∠ABD = 90°
also, ∠ABD = ∠CBD + ∠ABC
⇒ 90° = 4x + 52° + 8x - 10°
⇒ 12x = 48°
⇒ x = 4°
now,
∠CBD = 4x + 52°
= 4(4°) + 52°
= 68°
Answer:
![b=\frac{32}{3}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B32%7D%7B3%7D)
Step-by-step explanation:
![\frac{3}{4}b=8](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7Db%3D8)
Multiply both sides by 4:
![4\times \frac{3}{4}b=8\times4](https://tex.z-dn.net/?f=4%5Ctimes%20%5Cfrac%7B3%7D%7B4%7Db%3D8%5Ctimes4)
![3b=32](https://tex.z-dn.net/?f=3b%3D32)
Divide both sides by 3:
![\frac{3b}{3}=\frac{32}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3b%7D%7B3%7D%3D%5Cfrac%7B32%7D%7B3%7D)
![b=\frac{32}{3}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B32%7D%7B3%7D)
