Answer:
lacy = 8 jack= 24
Step-by-step explanation:
let x be lacys age
3x - 3 + x-3 = 14
3x+x -3 = 14 + 3 = 17
4x = 17 +3 = 20
x = 20/4 = 5
lacys age now = 5+3 = 8
jacks age now = 8 * 3 = 24
The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
The measure of m/EFH and m/EFG are 71 and 142 degrees
<h3>Bisection of angles</h3>
If a line bisects an angle, it divides the angle into two equal parts. If the line FH bisects EFG. hence;
<GFH = <HFG
Given the
Given that <GFH = 71 degrees, hence;
<EFG = 2(<GFH)
<EFG = 2(71)
<EFG = 142 degrees
Hence the measure of m/EFH and m/EFG are 71 and 142 degrees respectively
