Which statement is true?

Mathematics
1 answer:
ryzh [129]3 years ago
6 0

Answer:

C

Step-by-step explanation:

3x+4x-19+3x-1=180

10x=180+19

x = 199/10 = 19 (round to 20)

x = 20

<A= 20

<B= 80-19= 61

<C=. 59

The longest side is across from the largest angle. Draw the triangle ABC.

AC is across <C (the largest angle)

Myra wrote a computer program that had 75 lines of code. She realized that she could make the code more efficient and removed 20
jeka94

Answer:

Now Myra has 60 lines of code, no grid picture attached.

Step-by-step explanation:

If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.

75 divided by 5 is 15, and 75 - 15 = 60

Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?

Zarrin [17]

Answer:

Step-by-step explanation:

Let her total earnings be m

Amount left = (20m - 5m - 4m)/20

Amount left = 11m/20

Help me please thank you

S\frac{O}{H}C\frac{A}{H}T\frac{O}{A}   or   Sin\frac{Opposite}{Hypotenuse} Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}


The hypotenuse is the longest side of the triangle. The opposite is the side that is across from a point/angle. The adjacent is the side next to a point/angle.


At ∅ (pretend that's theta LOL), 17 is the hypotenuse, 8 is the opposite side, and 15 is the adjacent side.


So:

sin ∅ = Opposite/Hypotenuse

sin ∅ = \frac{8}{17}


cos ∅ = Adjacent/Hypotenuse

cos ∅ = \frac{15}{17}


tan ∅ = Opposite/Adjacent

tan ∅ = \frac{8}{15}
