B. 82 because complementary angles equal 90˚ combined and 90-8=82
The speed of Ingrid is needed so you can calculate how fast Hubert was going.
Hi there!
Since the triangle is equilateral, all of its sides are congruent. This means that to solve, we can set the two given equations equal to each other.
2(x - 8) = 1/2x + 8
2x - 16 = 1/2x + 8
1.5x - 16 = 8
1.5x = 24
x = 16
Now that we know what x is, we can plug that in for x in the equation for ZY.
2(16 - 8) = ZY
ZY = 2(8)
ZY = 16 units
And here is the work to show that XZ is also 16.
1/2(16) + 8 = XZ
XZ = 8 + 8
XZ = 16
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
19 x (12 + 2 + 3) = 323
323 - (2 x 2) - (3 x (14 + 2))
= 323 - 4 - 48
= 271
the answer is 268 hope this helps
