Answer:
27°
Step-by-step explanation:
XWY and VWY are supplementary
∴ XWY + VWY = 180°
∴ XWY = 180° - VWY
XYW and ZYW are supplementary
∴ XYW + ZYW = 180°
∴ XYW = 180° - ZYW
ΔXWY is a right triangle at X
∴ XWY + XYW = 90°
∴ 180° - VWY + 180° - ZYW = 90°
∴ 180° - 6x + 180° - 4x = 90°
∴ 360° - 10x = 90°
∴ 10x = 270°
∴ x = 27°

Answer:
The value of the variable 'b' is 3 and GH is 9
Step-by-step explanation:
Given:

H is between G and I
Such that G - H - I
To Find:
GH = ?
Solution:
On Substituting HI we get

Substituting 'b' in HI and GI we get


Now, by Line Addition Property we get

Substituting 'HI' and 'GI' we get

The value of the variable 'b' is 3 and GH is 9
Answer:
Mass=1068gr
Step-by-step explanation:
Volume= 7.5 cm x 2.53 cm x 7.15 cm=135.7cm^3
Density=7.87gr/cm^3
Mass=Density*Volume=135.7*7.87=1068gr
