In XYZ, XY=XZ
Find the length of XY of XYZ if XY=2a, YZ=3a+1, andXZ=5a-12
1 answer:
Answer: XY = 8
Step-by-step explanation:
The diagram of the triangle XYZ is shown in the attached photo.
XY=XZ. This means that two sides of the triangle are equal. Two angles are also equal. It means that the triangle XYZ is an isosceles triangle.
Since XY=XZ, then
2a = 5a - 12
Subtracting 2a from both sides of the equation,
2a - 5a = 5a - 12 - 5a
-3a = -12
a = -12/-3
a = 4
Therefore, the length of XY is 2a = 2×4 = 8

Step-by-step explanation:
The drill must go 3/8 of the way from one side of the sheet to the other. The depth that this drill must reach is found by multiplying 2.5 cm by 3/8:
25 3 5 3
----- * ----- = ------ * ------ = 15/16 cm

Answer:
10t - 16
Step-by-step explanation:
4(t + 2)+ 6(t - 4)
4t + 8 + 6t -24
10t - 16
If the axis is x then you go to y so (6, 5)
