The clock is showing 7:55 AM
Since it’s 12 minutes behind then the time would be 7:43 AM
Answer:
(-5/2, 3/2)
Step-by-step explanation:
[(-5.5+.5)/2, (9.1-6.1)/2)} = (-5/2, 3/2)
Answer:
A) ERROR
B) ∠C = 26°
Step-by-step explanation:
Houston, We have a problem!!! too much information
If we had a legit triangle, the law of sines would hold
19/sin138 = 8/sin20
28.395 = 23.390
as this is NOT an equality, the triangle does not exist as described.
IF it did, we'd get different results depending on which set we used
∠F = 180 - 138 - 20 = 22°
Law of sines
19/sin138 = DE/sin22 ⇒ DE = 19sin22/sin138 = <u>10.63697...</u>
or
8/sin20 = DE/sin22 ⇒ DE = 8sin22/sin20 = <u>8.762211...</u>
If we attempt to use Law of cosines
DE² = 19² + 8² - 2(19)(8)cos22 = <u>11.9639...</u>
so really none is correct because we attempt to use trig calculations to a non-triangle.
12) AC² = 15² + 19² - 2(15)(19)cos120
AC = 29.51270...
29.51270 / sin120 = 15/sinC
C = arcsin(15sin120/29.51270) = 26.1142... <u>26°</u>
<u>Answer:</u>
A. (x+5)
<u>Step-by-step explanation:</u>
We are given a quadratic expression
which we will factorize to see which of the given options is a binomial factor of it.
Finding the factors of 15 such that when added, they give a result of 8.

Therefore, we can see that
is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
1) 24 = 8a - 2a
24 = 6 a
24/6 = a
2) 5z + 4z = 36
