Answer:

Below in bold,

Step-by-step explanation:

m < JIK = the sum of the measure of the other 2 angles so we have:

140 - 6x = 20x - 10 + 8x - 20

140 + 10 + 20 = 20x + 6x + 8x

170 = 34x

x = 5.

m < JIL = 20(5) - 10 = 90 degrees.

m < LIK = 8(5) - 20 = 20 degrees.

m < JIK = 140 -5(5) = 110 degrees.

6. 5x = 8x - 4 (as QB is the bisector of < AQC.

Solve for x then substitute the value of x as in question 5.

Volume of a Prism Formula: V = lwh

l is length
w is width
h is height

Step-by-step explanation:

Step 1: Define

Identify variables

l = 13.8 cm

w = 4.5 cm

h = 5 cm

Step 2: Solve for V

Substitute in variables [Volume of a Prism Formula]: V = (13.8 cm)(4.5 cm)(5 cm)
Multiply: V = (62.1 cm²)(5 cm)
Multiply: V = 310.5 cm³
