Answer: 42.6
Step-by-step explanation:
First you would distribute the outer number to all the inner numbers:
6*3.1 + 6*4 = 18.6 + 24
Next you would add the numbers you just got:
18.6 + 24 = 42.6
Answer:
Step-by-step explanation:
We are given that a triangle ABC is a Right Angled Triangle. The side AB is hypotenuse, so the angle opposite to side AB which will be angle C is a Right Angle (measures 90 degrees)
We have the side length of all 3 sides. Based on this information, we can construct a triangle with given measures. The triangle is shown in the attached image.
We have to find the value of Sin(B). Sin of an angle is defined as:

The side opposite to angle B is AC with a length of 3 and hypotenuse is side AB with length 5. So Sin of angle B would be:

Answer:
Percy is incorrect
Step-by-step explanation:
I plugged in 9 and 8 for x and both of them did NOT solve it. The only number I know of that can solve it is -7. -7^2=49
-7 multiplied by 7 =-49
(49) + (-49) + 12 = 12
