First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
It technically would be y=3x-3 in the y=mx+b formula, but it could also be rewritten 3x-y=3. Hope this helps!
Answer:
100 miles in 20 minutes.
Step-by-step explanation:
300/60 = x/20
x = 300/60 * 20
x = 100
39.2 is what percent p of 112
39.2/112
39.2 ÷ 112 = 0.35
Convert to percent:-
0.35 × 100 = 35
35%
3.92 is 35% of 112.
I don't know honey, but I think it can be the 2nd choice, the answer...
