Answer:
Below in bold,
Step-by-step explanation:
5.
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.
7.719km
10 - 2.281 is 7.719
D. A'(1,-7), B'(2,-1), C'8,-2) and D'(7,-5)
Probably too late, but I took the quiz
1 5/8 inches
It can work out well to subtract integer portions and fractional portions, then combine the results.
(9 1/4) -(7 5/8) = 9 + 1/4 - 7 - 5/8
= (9 -7) +(1/4 -5/8)
= 2 + (2/8 -5/8)
= 2 -3/8
= 1 5/8
The piece of Myles' shoestring that broke off is 1 5/8 inches long.
