Answer:
90 degrees
Step-by-step explanation:
A triangle equals 180
180 - 60
= 120
120 - 30
= 90
Also you can easily get the answer without doing any math because you can see the angle is a right angle
Right angles equal 90
Hope this helps dude
The correct answer is 100 feet, because of the SAS Postulate
A#b=ab+a+b
Replace a with 2 and b with 5
2#5=2*5+2+5=17
Answer C
The answer is 16 3/8.
So, to find out the total weight we have to add them all up. However, since we need a common denominator to add them up, we have to change the denominator of the first two mixed fractions, 2 1/2 and 1 1/2. Since we know that 2 is a factor of 8, we know that we can use 8 as the common denominator. The third mixed fraction already has a denominator of 8 so we just have to change the denominator of, 2 1/2 and 1 1/2. To do this, we just have to multiply the numerator and denominator by 4 to get, 2 4/8 and 1 4/8. Next, we can add them all up. We first add the fraction part, 4/8 + 4/8 + 3/8, which would give us 11/8, which can be turned into 1 3/8. Finally, we just have to add the whole numbers and 1 3/8, 2 + 1 + 12 + 1 3/8, to get 16 3/8.
Comment any questions if you still need help.
The first thing you should know is that to represent a parabola you need at least three points, which are given by the enunciation of the problem. Therefore, the function that best represents the parabola is: y = -x^2 - 2x + 3
